Chevrolet Camaro Engine Crankshaft Position Sensor Guide (2009-2024)
Spot the signs of a failing crank sensor in your Camaro and learn how to choose the right replacement part.
- A failing sensor will almost always trigger a Check Engine Light with codes P0335 or P0336.
- For V8 models, the starter motor must often be removed to access the sensor, increasing labor time.
- Stick with OEM brands like ACDelco or Delphi for this critical part to ensure reliability and avoid repeat repairs.
- A 'Crankshaft Variation Relearn' procedure with a proper scan tool is mandatory after replacement to clear codes and ensure proper engine function.
Symptoms of a Bad Crankshaft Position Sensor in a Camaro
A failing crankshaft position sensor can cause a range of problems, from annoying to leaving you stranded. The most common sign is the Check Engine Light coming on. If you have a code reader, you'll likely see codes P0335 (Crankshaft Position Sensor 'A' Circuit Malfunction) or P0336 (Crankshaft Position Sensor 'A' Circuit Range/Performance).
Other common symptoms include:
- Engine Stalling: The engine may stall unexpectedly, especially at low speeds or when idling. This can be dangerous in traffic.
- Hard Starting or No-Start: Your Camaro might take longer than usual to start, or it may crank but refuse to fire up at all. This happens because the ECM doesn't know when to fire the spark plugs and injectors.
- Rough Idle and Misfires: You might feel a noticeable vibration or shuddering when the car is stopped. An erratic sensor signal can cause the engine to misfire.
- Poor Acceleration: The car may feel sluggish or hesitate when you press the gas pedal.
- Reduced Fuel Economy: Inefficient timing for fuel injection means your engine will use more gas than necessary.
Heat is the Enemy
On V8 models especially, the sensor is located near the hot exhaust system. Over time, this intense heat can cook the sensor's internal electronics, leading to failure. Some owners with aftermarket headers report premature failures for this reason.
Choosing the Best Aftermarket Sensor for Your Camaro
When it comes to critical sensors like the crankshaft position sensor, quality matters. While many brands are available, they generally fall into a few tiers.
Tier 1: OEM and OEM-Equivalent Brands
- ACDelco (GM Genuine): This is the original part your Camaro was built with. It offers the highest likelihood of perfect fit and function.
- Delphi: Delphi is often the original equipment manufacturer (OEM) that makes the parts for GM. Choosing Delphi is essentially like buying the genuine part without the GM box, often at a lower price.
Tier 2: Reputable Aftermarket Brands
- NGK/NTK: Known for their quality ignition components and sensors, NTK is a highly trusted brand in the aftermarket.
- Hitachi: As a major electronics manufacturer, Hitachi produces reliable sensors that often meet or exceed OEM standards.
- Standard Motor Products (SMP): A long-standing name in aftermarket parts, SMP offers a solid balance of quality and value.
- Walker Products: Another established brand that provides dependable sensors for a wide range of vehicles.
Tier 3: Economy Brands
- Dorman, Spectra, and others: These brands offer a budget-friendly option. While they can work, forum discussions sometimes mention a higher chance of out-of-the-box failures or shorter lifespans compared to premium brands. For a critical sensor that can leave you stranded, it's often worth spending a little more for a top-tier part.
Crankshaft Variation Relearn Procedure
After replacing the crankshaft position sensor on a GM vehicle, a "Crankshaft Variation Relearn" (also called a CASE relearn) is required. This procedure uses a scan tool to synchronize the new sensor with the ECM. If this step is skipped, your Camaro may run poorly and will likely keep the P0336 trouble code active. Most repair shops can perform this, and some high-end DIY scan tools also have this function.
Chevrolet Camaro Crankshaft Sensor Replacement Cost
The cost to replace the sensor depends on your vehicle's engine and whether you do it yourself or use a repair shop.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Sensor | $22 - $87 |
| New OEM (ACDelco) Sensor | $45 - $110 |
| Shop Labor | $100 - $250 |
| Total Professional Replacement | $122 - $360 |
Frequently Asked Questions
Where is the crankshaft position sensor located on a Chevrolet Camaro?
The location varies by engine. On V6 models (like the 3.6L LLT), it's often accessible through the passenger side wheel well. 🎬 Watch this step-by-step guide for replacing the sensor on V6 models. On V8 models (like the LS3 and LT1), it is typically located on the passenger side of the engine block, above and behind the starter motor. 🎬 See how to access and replace the sensor on V8 models. This can make replacement more difficult, as the starter often needs to be removed for access.
Are there any recalls for the Camaro crankshaft position sensor?
There are no specific recalls for the crankshaft position sensor itself. However, there have been recalls for other issues, such as ignition switches on 2010-2014 models and transmission problems on 2020-2022 models, that could cause stalling. There is also a Technical Service Bulletin (TSB PIP3423P) for some 2010-2015 V6 models where the crankshaft reluctor ring can move, causing similar codes (P0016, P0017, etc.) and requiring crankshaft replacement.
What's the difference between a crankshaft and a camshaft sensor?
They work together but measure different things. The crankshaft sensor tracks the rotation of the crankshaft at the bottom of the engine. The camshaft sensor tracks the position of the camshaft(s) at the top of the engine, which controls the valves. Both signals are needed by the ECM for precise timing. On the Camaro, the cam sensors are typically located on the front of the engine.
Do I have to disconnect the battery to replace the sensor?
Yes, it is highly recommended. Any time you work on your vehicle's electrical system, you should disconnect the negative battery terminal to prevent short circuits and protect the vehicle's sensitive electronics.

The sensor is a Hall-effect type sensor that reads a reluctor wheel on the crankshaft to generate a digital signal for the ECM. It is typically secured by a single 10mm bolt. The electrical connector features a red locking clip that must be disengaged before removal.
