P0019 on 2015-2021 Ford Edge: Crank-Cam Correlation Causes and Fixes

What's Unique About the 2015-2021 Ford EDGE

For this generation of Ford Edge, across all its V6 and EcoBoost engines, the Variable Camshaft Timing (VCT) system is particularly sensitive to oil condition. Ford has issued multiple Technical Service Bulletins (TSBs) stating that small debris in the engine oil can cause the VCT solenoids to stick, directly triggering codes like P0019. This makes regular, high-quality oil changes more critical than on many other vehicles and points to the VCT solenoid as a primary suspect before considering more complex timing chain issues. TSB SSM 50067 even advises technicians to attempt cycling the solenoid with a scan tool 🎬 Watch: 4 DIY methods to fix the P0019 code to clear debris before replacing any parts.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Check Engine Light illuminated
• Rough or unstable engine idle
• Engine hesitation or stumbling during acceleration
• Reduced fuel economy
• Engine may be difficult to start or may stall at low speeds
• Rattling or ticking noise from the engine, especially on startup

Most Likely Causes

1. Sticking/Failing VCT Solenoid (Bank 2 Exhaust) 🔴 High Probability Multiple Ford TSBs (#SSM 50067, #SSM 47170, #SSM 48423) state this is a common issue caused by small debris in the oil. The solenoids have fine mesh screens that can become clogged, impeding oil flow.
   How to confirm: After checking oil, this is the next step. A mechanic can command the solenoid with a scan tool to check response. A common DIY diagnostic is to swap the Bank 2 exhaust solenoid with the Bank 2 intake solenoid (they are often the same part) and see if the code changes to P0018. If it does, the solenoid is confirmed bad.
   Typical fix: Replace the Bank 2 exhaust VCT solenoid. An engine oil and filter change is highly recommended at the same time to remove the debris that caused the failure.
   Est. part cost: $40-$100
2. Low or Dirty Engine Oil 🟡 Medium Probability The VCT system is entirely dependent on oil pressure to adjust cam timing. Ford TSBs explicitly state to perform an oil and filter change before other component diagnostics for these codes.
   How to confirm: Check the oil level on the dipstick and inspect its color and consistency. If it's low, past its change interval, or very dark/gritty, this is a likely contributor.
   Typical fix: Perform an oil and filter change using the correct grade of oil specified by Ford (e.g., SAE 5W-30 for many EcoBoost engines). Clear the codes and drive to see if P0019 returns.
   Est. part cost: $50-$90
3. Faulty Camshaft Position Sensor (Bank 2 Exhaust) ⚪ Low Probability → Shop Engine Camshaft Position Sensor
   How to confirm: Test the sensor's voltage output with a multimeter to see if it's within spec. Check for a consistent signal using an oscilloscope. A failing sensor may also trigger other codes like P0349.
   Typical fix: Replace the Bank 2 exhaust camshaft position sensor. It is located on the valve cover of the rear cylinder bank. 🎬 See this quick guide on changing Ford Edge camshaft sensors
   Est. part cost: $30-$80

Rare But Worth Checking

• Stretched Timing Chain or Failed Tensioner: → Shop Engine Timing Chain This is a more serious mechanical issue. It's less common than a solenoid failure but can happen on higher-mileage vehicles (typically over 100,000 miles). It often presents with a rattling noise on startup that lasts for a few seconds. This is a labor-intensive repair, often costing $2,000-$4,000+ as it may require significant engine disassembly.
• Damaged Camshaft Phaser: → Shop Engine Camshaft The phaser is the gear on the end of the camshaft that is hydraulically adjusted by the VCT solenoid. If it fails mechanically, gets stuck, or its internal locking pin breaks, it can cause a correlation code. This is a more involved repair than a solenoid replacement.
• Wiring or Connector Issue: A damaged wire or corroded connector for either the crankshaft sensor, camshaft sensor, or VCT solenoid can interrupt the signal to the PCM. A visual inspection and wiggle test of the harness is a good starting point.

Diagnosis Steps

1. Check Engine Oil: Verify the oil level is correct and the oil is clean and of the proper viscosity. If low or dirty, perform an oil change, clear the code, and drive the vehicle to see if the code returns. This is the first step recommended by Ford TSBs.
2. Scan for Other Codes: Check for any other related trouble codes that could provide more clues (e.g., P0018, P0349).
3. Inspect Wiring: Visually inspect the wiring harnesses and connectors for the Bank 2 (radiator side) exhaust camshaft sensor and VCT solenoid. Look for any signs of damage, corrosion, or loose connections.
4. Test/Swap the VCT Solenoid: Using a capable scan tool, command the Bank 2 exhaust VCT solenoid to activate. Alternatively, swap the exhaust VCT solenoid with the intake VCT solenoid on the same bank. Clear codes and drive. If the code changes to P0018, the solenoid is faulty 🎬 Watch: Step-by-step VCT solenoid replacement walkthrough and needs replacement.
5. Test the Camshaft Position Sensor: If the solenoid is confirmed good, check the camshaft position sensor's signal with a multimeter or oscilloscope to ensure it's sending a correct and stable signal to the PCM.
6. Inspect Timing Components: If all sensors and solenoids are working, the next step is a more in-depth mechanical inspection of the timing chain, guides, and phasers for wear, stretch, or damage. This often requires significant disassembly and is best left to a professional.

Related Codes That Often Appear With This One

• P0017 — Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor 'B'). If both P0017 and P0019 appear, it points to an issue affecting the exhaust cams on both banks, strengthening the possibility of a systemic problem like low oil pressure or a stretched primary timing chain.
• P0018 — Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor 'A'). This points to the intake camshaft on the same bank. Seeing P0018 and P0019 together strongly suggests an issue with Bank 2 specifically, such as a problem with the oil supply to that head or a secondary timing chain issue on that bank.
• P0349 — Camshaft Position Sensor 'B' Circuit Intermittent (Bank 2). This code points more directly to a failing sensor or wiring issue on that specific sensor circuit, rather than a correlation fault.

Technical Service Bulletins (TSBs) & Recalls

• SSM 54366: Mentions P0019 among other DTCs on 2015-2021 Ford vehicles and refers to specific pinpoint tests.
• SSM 50067: States that P0019 on 2015-2021 Fords may be due to small debris causing the VCT solenoid to stick and advises cycling the solenoid to clear it before replacement.
• SSM 47170: Similar to SSM 50067, points to debris in oil causing a stuck VCT solenoid.
• TSB-16-0093: Notes that P0019 can appear on very low-mileage vehicles.
• SSM 48423: Again, highlights that P0019 on 2015-2020 Fords can be caused by a VCT solenoid sticking due to debris.

Platform-Specific Known Issues

• Ford TSBs Point to VCT Solenoids: Ford has issued several Technical Service Bulletins (TSBs) related to a group of VCT codes, including P0019. TSBs #SSM 54366, #SSM 50067, #SSM 47170, and #SSM 48423 all point to the potential for small debris in the engine oil to cause the VCT solenoids to stick, leading to these timing correlation faults.
• Real-World Repair Story: On fordedgeforum.com, a user with a 2017 Edge 3.5L reported a P0019 code. Following advice from the forum, they started with the simplest fix: replacing the Bank 2 (firewall side) VCT solenoids and performing an oil change. This resolved the code without needing to investigate the more expensive timing chain components, highlighting the community consensus to always start with oil and solenoids.

Mechanic-Grade Diagnostic Values

• VCT Solenoid (OCV) Resistance — expected: 6.9 to 7.9 Ohms at 68°F (20°C). Some sources state a general range of 5-20 Ohms is acceptable for many VVT solenoids.. Failure: A reading of infinite resistance (OL) indicates an open coil, while a very low reading (under 2 Ohms) indicates a short. In either case, the solenoid should be replaced.
• Camshaft Position Sensor (3-wire Hall effect) Voltage — expected: With the key on, engine off, and sensor connected: Power wire should have ~5V, Ground wire should read 0V, and the Signal wire should also have ~5V.. Failure: When a metal object (like a wrench) is passed in front of the sensor tip, the signal voltage should drop to 0V momentarily. If the voltage does not change, the sensor is likely faulty.
• VCT Advance Error PID (using Ford IDS) — expected: While in closed-loop operation at idle, the VCT_ERR PIDs for each bank should be close to 0 degrees.. Failure: A sustained deviation of more than +/- 5 degrees indicates a correlation problem that the PCM is trying to correct. This points towards a sticking phaser or solenoid.

Scan Tool Commands That Help

• Ford IDS (or equivalent high-level scanner): VCT Solenoid Actuator Test / Bidirectional Control — This command allows a technician to manually activate the Bank 2 exhaust VCT solenoid while the engine is running. If the engine hesitates or stalls when the solenoid is commanded on, it confirms the solenoid is mechanically capable of moving. If there is no change in engine operation, the solenoid is likely stuck or clogged.
• Ford IDS (or equivalent high-level scanner): Monitor VCT_ADV_ERR PID (Variable Cam Timing Advance Error) — This live data parameter shows the difference between the desired camshaft angle and the actual camshaft angle. It is the most direct way to see the timing error in real-time. A consistent error value outside of a few degrees confirms a correlation fault and helps differentiate between an intermittent glitch and a hard failure.

Wiring & Ground Locations

• Bank 2 Location — For the transverse mounted engines in the Ford Edge, Bank 2 is the cylinder bank located closer to the radiator (front of the vehicle).. P0019 specifically refers to Bank 2. Misidentifying the bank will lead to diagnosing and replacing components on the wrong side of the engine.
• Sensor 'B' Location — Sensor 'B' universally refers to the exhaust camshaft position sensor or its circuit.. This code is for the exhaust cam ('B'), not the intake cam ('A'). The sensors and VCT solenoids are distinct for intake and exhaust and must be diagnosed separately.
• Engine Harness Ground — A key ground point for the engine harness is often located on the left (driver's side) fender in the engine compartment.. A poor ground connection can cause erratic voltage signals from the cam and crank sensors, leading to false correlation codes. Ensuring this ground is clean and tight is a critical step in diagnosing electrical faults.

Real Owner Repair Stories

• Ford Edge Forum (2017 Ford Edge 3.5L) — Check Engine Light with code P0019.
  ❌ Tried (didn't work) Initial diagnosis pointed towards potential timing chain issues.
  ✅ What actually fixed it The owner replaced the VCT solenoids on Bank 2 (firewall side in this user's description, though typically it's the radiator side) and performed an oil change. This resolved the P0019 code without requiring more extensive mechanical repairs.

Model Year Variations Within This Range

• 2019-2021: For the 2019 model year refresh, Ford discontinued the naturally aspirated 3.5L V6 engine. The standard engine became the 2.0L EcoBoost I4, and the Edge Sport was replaced by the Edge ST with a 2.7L EcoBoost V6. The transmission was also updated from a 6-speed to an 8-speed automatic. While the P0019 code can still occur on these engines, the specific part numbers for sensors/solenoids and diagnostic procedures may differ from the earlier 3.5L V6.
