P0014 on 2009-2010 Saturn SKY: Exhaust Cam Timing Causes and Fixes

What's Unique About the 2009-2010 Saturn SKY

The Ecotec engines in the Saturn SKY (and its Pontiac Solstice sibling) are well-known for issues with the camshaft position actuator solenoids. Failure is so common that many owners consider them a routine maintenance item. The issue is often caused by engine oil sludge or debris clogging the small screens on the solenoids, which disrupts the oil flow needed to adjust cam timing. While a timing chain issue can also cause this code, the solenoids are a much more frequent and simpler point of failure on this specific platform.

Symptoms You May Notice

• Check Engine Light is on
• Rough or uneven idle
• Sluggish acceleration and lack of power
• Hard starting
• Engine may stall at low speeds
• Reduced fuel economy
• A short, sharp rattle from the front of the engine on startup, lasting 2-5 seconds [TSB #PIP4716F]
• Failed emissions test

Most Likely Causes

1. Faulty Exhaust Camshaft Position Actuator Solenoid 🔴 High Probability → Shop Engine Camshaft This is a widely documented failure point on GM Ecotec engines due to sensitivity to oil contamination and debris clogging the internal screens.
   How to confirm: The easiest test is to swap the exhaust solenoid with the intake solenoid. They are identical parts. Clear the codes and drive. If the code changes to P0011 (Intake Camshaft Position), the solenoid is confirmed bad. The exhaust solenoid is the one located towards the rear of the engine cover (closer to the firewall), while the intake is at the front.
   Typical fix: Replace the exhaust camshaft position actuator solenoid. It is held in by a single 10mm bolt and can be replaced in about 10 minutes. 🎬 Watch: A step-by-step guide to replacing the solenoid on your Sky.
   Est. part cost: $25-$60
2. Low or Dirty Engine Oil 🟡 Medium Probability The VVT system is operated by oil pressure. Contaminated or low oil can clog the solenoid screens and passages, preventing proper operation. The 2.4L LE5 engine, in particular, can be prone to oil consumption.
   How to confirm: Check the oil level on the dipstick and inspect its condition. If the oil is dark, gritty, or below the 'add' line, this is a likely contributor. This should be the very first check performed.
   Typical fix: Perform an oil and filter change using the correct viscosity full synthetic oil (5W-30). This should be done before or at the same time as replacing a solenoid.
   Est. part cost: $40-$80
3. Stretched Timing Chain or Failed Tensioner ⚪ Low Probability → Shop Engine Timing Chain While less common than solenoid failure, Ecotec timing chains can stretch over time, and tensioners can fail, causing slack and incorrect timing readings. Models from 2007-2008 used an earlier timing set design that was more prone to failure.
   How to confirm: This is a more advanced diagnosis. A startup rattle that persists is a strong indicator. [TSB #PIP4716F] A mechanic would need to remove the valve cover to inspect for chain slack or inspect the timing components, which is a labor-intensive job.
   Typical fix: Replace the timing chain, guides, and tensioner as a kit. It is highly recommended to use the updated GM tensioner design. This is a significant repair, often costing $800-$1500.
   Est. part cost: $150-$300

Rare But Worth Checking

• Failed Camshaft Phaser (Actuator): → Shop Engine Camshaft The gear-like actuator on the end of the camshaft itself can fail mechanically, getting stuck in an advanced position. TSB #PIP4716F notes that if a startup rattle is verified to be from the actuator, it must be replaced. This is much less common than a solenoid failure and more expensive to repair.
• Faulty Camshaft Position Sensor: → Shop Engine Camshaft Position Sensor It is possible for the sensor that reads the camshaft's position to fail, but this is far less common than the solenoid that controls the position. Often misdiagnosed as the primary failure.

Diagnosis Steps

1. Check Engine Oil: Verify the oil level is full and the oil is clean and of the correct 5W-30 full synthetic specification. If low or dirty, perform an oil and filter change, clear the code, and see if it returns.
2. Inspect Solenoid Connectors: Ensure the electrical connectors for both the intake and exhaust VVT solenoids are secure and free of corrosion or oil contamination.
3. Swap the Solenoids: The intake and exhaust solenoids are identical and interchangeable for testing. They are located on the front of the engine cover, held by 10mm bolts. The intake solenoid is towards the front of the car, the exhaust is towards the back/firewall.
4. Re-scan for Codes: Clear the original P0014 code. Drive the vehicle and re-scan. If code P0011 appears, the solenoid you moved to the intake position is faulty and needs to be replaced.
5. Test the Solenoid (Optional): If you have a multimeter, you can test the solenoid's resistance. A typical reading should be between 8 and 13 ohms. However, a solenoid can pass a resistance test but still be mechanically stuck.
6. Inspect Timing Chain: If a new solenoid and fresh oil do not resolve the code, and especially if you hear a persistent rattling noise, the next step is a more involved inspection of the timing chain, guides, and tensioner, which may require a professional mechanic.

Parts You'll Likely Need

• Engine Variable Valve Timing (VVT) Solenoid / Camshaft Position Actuator Solenoid (OEM #12655421 (Exhaust), 12655420 (Intake) - Note: The parts are identical and interchangeable for testing.) — This is the most frequent cause of P0014 on the Saturn SKY. It gets clogged with oil sludge and fails to properly control cam timing.
  Trusted brands: ACDelco (OEM), Dorman (e.g., 917-216 for exhaust, 917-215 for intake)
  OEM price range: $40-$60
  Aftermarket price range: $25-$45

Related Codes That Often Appear With This One

• P0013 — This code indicates an electrical circuit problem with the same exhaust camshaft actuator solenoid. Seeing both P0013 and P0014 together strongly points to a bad solenoid or its wiring connector.
• P0011 — This is the equivalent code for the intake camshaft ('A' Camshaft). If you swap the solenoids for diagnosis and P0014 disappears and P0011 appears, you've confirmed the solenoid is the faulty part.
• P0016 & P0017 — These are crank/cam correlation codes. If P0014 is present with these, it increases the likelihood of a more serious mechanical timing issue, like a stretched timing chain.

Technical Service Bulletins (TSBs) & Recalls

• PIP4716F: Mentions a rattle noise at startup and lists P0014 as a possible diagnostic trouble code, pointing to either cam actuators or contaminated oil/solenoids.
• PIP4469E: An older TSB that also discusses DTCs P0011, P0014, P0016, and P0017 in relation to hesitation or stall conditions on these engines.

Platform-Specific Known Issues

• A Technical Service Bulletin (TSB #PIP4716F) was issued for a short, sharp rattle noise from the front of the engine at start up, which may be accompanied by DTC P0014, P0011, P0016, or P0017. The TSB suggests this could be an issue with the cam actuators not parking properly, requiring replacement. It also advises inspecting the VVT solenoids for debris and performing multiple oil changes if contamination is found.

Mechanic-Grade Diagnostic Values

• VVT Solenoid (Camshaft Actuator) Resistance — expected: 8 to 13 Ohms at room temperature.. Failure: A reading outside this range, an open circuit (infinite resistance), or a wildly fluctuating reading when wiggling the connector indicates a bad solenoid.
• Scan Tool Live Data: Desired vs. Actual Camshaft Angle — expected: At idle with a warm engine, both 'Desired' and 'Actual' exhaust cam angle should be at or very near 0 degrees. The values should closely mimic each other as engine RPM changes.. Failure: With code P0014, the 'Actual' angle will be significantly advanced (a positive number) while the 'Desired' angle is 0. This indicates the phaser is stuck in an advanced position.
• VVT Solenoid Connector Voltage (Key On, Engine Off) — expected: On the 2-pin connector, one pin should have 12V (battery voltage) and the other is the control wire from the ECM.. Failure: Absence of 12V power points to a fuse or wiring issue. The control wire is pulse-width modulated (PWM) and is best tested for activity with a graphing multimeter or oscilloscope while the engine is running.

Scan Tool Commands That Help

• Tech2 / GDS2 (GM Dealer Tools): Engine Output Controls > Camshaft Position Actuator Solenoid — This bidirectional control allows a technician to manually command the solenoid to a specific duty cycle (e.g., 10%, 20%) while watching the 'Actual Camshaft Angle' on live data. If the angle changes with the command, the solenoid and phaser are likely functional, pointing towards a wiring or oil pressure issue. If the angle does not change, it confirms a fault in the solenoid or phaser.
• Most professional scan tools: Camshaft Position Relearn / Reset — For the Saturn SKY's Ecotec engine, a specific VVT relearn procedure is generally NOT required after replacing the solenoids. The ECM's adaptive learning will adjust to the new parts automatically over a few drive cycles. Some sources mention a generic drive cycle to speed this up, but it is not a mandatory step.

Wiring & Ground Locations

• G103 — Located at the left rear of the engine compartment on the cowl, above the brake booster.. This is a primary ground for the Body Control Module (BCM) and the Data Link Connector (DLC). A poor connection here can cause various communication and electrical issues, though it's less likely to be a direct cause of an isolated P0014.
• G105 — Located at the left front of the engine compartment, often near the cooling fan relays.. This ground serves several components in the front of the engine bay. While not a direct ground for the ECM, poor engine bay grounds can create electrical noise that may affect sensor readings.
• ECM (Engine Control Module) — Located in the left rear corner of the engine compartment.. The ECM directly controls the VVT solenoids. The wiring harness runs from the ECM to the solenoids on the front of the engine. Damage to this harness could cause P0013 (circuit fault) or P0014.

Real Owner Repair Stories

• SkyRoadster.com forum user (Saturn Sky (engine not specified, but platform has LE5/LNF)) — P0014 code and a startup rattle noise.
  ❌ Tried (didn't work) Replacing both intake and exhaust VVT solenoids.
  ✅ What actually fixed it The final repair was replacing the timing chain, guides, and tensioner. This highlights that while solenoids are common, they are not the only cause, especially when a persistent rattle is present.
• YouTube video by 'WatchJRGo' (2007 Saturn Sky Redline (2.0L LNF Turbo)) — Check Engine Light with codes P0010 and P0011 (Intake side faults).
  ❌ Tried (didn't work) Initial diagnosis pointed directly to the common solenoid failure.
  ✅ What actually fixed it Replacing the intake VVT solenoid resolved the codes. The video confirms the high failure rate and the simplicity of the DIY replacement with a single 10mm bolt.

When the Usual Fixes Don't Work

• While the most common fix for P0014 is replacing the VVT solenoid, there are documented cases where this does not solve the problem. In instances accompanied by a persistent startup rattle, the root cause has been found to be a stretched timing chain and/or a failed tensioner. In these cases, replacing the solenoids is an unnecessary expense, and the true, more intensive mechanical repair of the timing system is required to resolve the code.

OEM Part Supersession History

• 12655421 (Exhaust), 12655420 (Intake) → 12679100 (Exhaust), 12679099 (Intake) — The updated parts are believed to have improved internal valving and better resistance to contamination from oil debris and sludge, addressing the common failure mode of the original design.

Model Year Variations Within This Range

• 2009-2010: No significant variations in the VVT system, causes, or fixes for P0014 have been identified between the 2009 and 2010 model years for the Saturn SKY. The primary Ecotec engine updates occurred prior to this period.
