Chevrolet SSR Crankshaft Position Sensor Guide (2003-2006)
Everything you need to know before replacing the crankshaft position sensor on your 2003-2006 SSR.
- A failed sensor will likely cause a no-start condition, leaving you stranded.
- The sensor is located above the starter on the passenger side; the starter must be moved for access.
- A 'Crankshaft Position Variation Learn' procedure with a scan tool is required after replacement.
- For reliability, choosing a premium brand like Delphi or NGK/NTK is strongly recommended over budget options.
Understanding Crankshaft Position Sensor Failure in Your SSR
A failing crankshaft position sensor is a common issue on many vehicles, including the LS-based engines in the 2003-2006 Chevrolet SSR. This sensor operates in a high-heat environment and can fail over time, leading to a range of engine performance problems. Symptoms often start as intermittent issues, such as stalling when hot, but can quickly lead to a no-start condition that will leave you stranded.
Symptoms of a Failing Crankshaft Sensor
- Check Engine Light: The most common sign is a check engine light with codes P0335 (Crankshaft Position Sensor 'A' Circuit Malfunction) or P0336 (Crankshaft Position Sensor 'A' Circuit Range/Performance).
- Engine Will Not Start: The engine will crank over but will not start because the ECM is not receiving a signal to fire the spark plugs and injectors.
- Sudden Stalling: The engine may stall without warning while driving, especially after it has warmed up. It may or may not restart until it has cooled down.
- Rough Idle and Engine Misfires: Incorrect timing information can cause the engine to run rough, vibrate, or misfire.
- Poor Acceleration: You may notice a significant lack of power and sluggish acceleration.
Choosing the Right Aftermarket Part
For a critical sensor like this, brand quality matters. While many options are available, they are not all created equal. Using a low-quality sensor can lead to incorrect readings, premature failure, and repeat repairs.
- Premium Brands (OE-Equivalent): Delphi is widely believed to be the original equipment manufacturer for many GM electronics, making their parts a direct equivalent to the factory sensor. NGK (under their NTK sensors line) is another top-tier manufacturer known for quality and reliability. These are the most recommended choices.
- Reputable Aftermarket Brands: Standard Ignition (SMP) and Hitachi are well-known aftermarket brands that generally offer good quality and are considered a reliable choice if premium brands are not available.
- Value Brands: Brands like Dorman, Walker Products, and other lower-cost options are available. While they meet the basic fitment, they are built to a price point and may not have the same durability or precise calibration as premium options.
Cost to Replace the SSR Crankshaft Position Sensor
Below are typical cost ranges you can expect. Prices can vary based on your location and the specific part brand you choose.
| Item | Estimated Cost |
|---|---|
| New OEM (ACDelco/GM) | $75 - $100 |
| New Aftermarket | $27 - $97 |
| Shop Labor | $135 - $200 |
| Total Professional Replacement | $231 - $369 |
Replacement Overview & Special Procedures
The crankshaft sensor on the SSR is located on the passenger side of the engine block, positioned just above the starter. To access it, the starter motor must be unbolted and carefully moved out of the way. The sensor itself is then held in by a single 10mm bolt.
Required: Crankshaft Position Variation Learn Procedure
After replacing the sensor, you must perform a "Crankshaft Position Variation Learn" (also known as a case relearn). This procedure calibrates the new sensor with your vehicle's computer. It requires a compatible bi-directional scan tool. Failure to perform the relearn can result in a persistent check engine light, rough running, and misfires. Most DIY mechanics do not own the required tool, so you may need to take the vehicle to a repair shop to have this procedure completed after installing the part.
Frequently Asked Questions
Is there a recall on the SSR for the crankshaft position sensor?
No. While GM issued a recall for crankshaft position sensors on some 2001 model year trucks with the 8.1L engine, this recall does not apply to the 2003-2006 Chevrolet SSR, which uses a different engine (5.3L or 6.0L). There are no active recalls for this specific part on the SSR.
Is the crankshaft sensor the same for all 2003-2006 SSR models?
Yes. Both the 5.3L (2003-2004) and 6.0L (2005-2006) engines used in the SSR are from the same GM LS engine family and use the same 24x reluctor wheel and corresponding black crankshaft position sensor. The correct OEM part number is GM 12560228 or ACDelco 213-354.
What is a CKP Variation Learn and why is it so important?
A CKP Variation Learn is a calibration process performed with a professional scan tool. It allows the engine computer (ECM) to learn the precise position of the new sensor relative to the crankshaft's reluctor wheel. Every sensor and wheel has tiny manufacturing variations. The relearn procedure compensates for these, ensuring accurate timing for smooth operation and misfire detection. Without it, the ECM may think the engine is misfiring when it isn't.
Can I make a common mistake when ordering this part?
The most common mistake is confusing the 24x sensor (black) used on the SSR with the 58x sensor (gray) used on later generation LS engines. For the 2003-2006 SSR, you need the 24x sensor. Always verify the part number, which is typically GM 12560228.
