Guide to the 2006-2009 Pontiac Torrent Engine Crankshaft Position Sensor
Fix stalling, no-start conditions, and Check Engine Light warnings by understanding and choosing the right crankshaft sensor for your Torrent.
- A failing sensor is a common cause of stalling or no-start issues in the Pontiac Torrent.
- The Check Engine Light with code P0335 is a primary indicator of a bad crankshaft sensor.
- For reliability, choose an OEM brand like ACDelco or a premium aftermarket brand like Delphi.
- A special 'crankshaft variation relearn' procedure with a scan tool is required after replacement.
Symptoms of a Failing Crankshaft Position Sensor in a Pontiac Torrent
When the crankshaft position sensor in your 2006-2009 Torrent starts to fail, the signs can range from annoying to leaving you stranded. Because this sensor is essential for engine timing, a bad signal can cause serious problems.
- Check Engine Light: This is often the first warning. A scan tool will likely show code P0335, which points directly to a problem in the crankshaft position sensor circuit.
- Engine Stalling: The engine may stall unexpectedly, either while idling at a stoplight or while driving. This is a serious safety concern.
- Difficulty Starting or No-Start: Your Torrent may take longer than usual to start, or it may not start at all. The engine cranks, but the computer doesn't have the information it needs to begin ignition and fuel injection.
- Rough Idle and Misfires: The engine may run unevenly, shake, or vibrate because the timing is off.
- Poor Acceleration: You might notice the vehicle feels sluggish or lacks power when you press the gas pedal.
- Reduced Fuel Economy: Incorrect timing can cause the engine to burn more fuel than necessary.
Choosing the Right Aftermarket Sensor for Your Torrent
For a critical component like the crankshaft position sensor, part quality matters. While many brands are available, they generally fall into different quality tiers. For a GM vehicle like the Pontiac Torrent, sticking with brands known for their OE (Original Equipment) connections is a safe bet.
Premium Brands (OEM-Quality)
These brands are either the original supplier to GM or are known for meeting or exceeding OEM standards. They are the most reliable choice for fit and long-term performance.
- ACDelco: As GM's own parts brand, ACDelco is the direct OEM replacement. Choosing ACDelco ensures you get a part with the same performance and durability as the one your Torrent was built with.
- Delphi: Delphi was a major parts manufacturer for GM and is often the original supplier for many electronic components. A Delphi sensor is an excellent OEM-quality alternative.
- Bosch: A top-tier global automotive supplier known for high-quality electronics and sensors.
Quality Aftermarket Brands
These brands offer a good balance of quality and value. They are reputable and a solid choice for most repairs.
- Standard Ignition (SMP): A long-standing and respected aftermarket manufacturer with a reputation for producing reliable sensors.
- Walker Products: Known for engine management and fuel system components that are designed to match OE fit and function.
- Hitachi: An established OEM supplier for many automakers, known for quality electronics.
- Beck Arnley: Focuses on sourcing parts that match the original form, fit, and function for specific vehicles.
Economy Brands
These brands are budget-friendly options. While they can get your vehicle back on the road, their long-term reliability and manufacturing consistency may not match that of premium brands. For a sensor that can leave you stranded, it's often worth investing in a higher-tier part.

After replacing the crankshaft position sensor on a GM vehicle like your Torrent, a procedure called a "Crankshaft Position System Variation Learn" (or CASE relearn) is required. This calibrates the new sensor to the engine computer. If this step is skipped, your Check Engine Light may stay on (with a code like P0315), and the engine may run rough. This procedure must be done with a compatible professional-grade scan tool. 🎬 Learn how to perform the mandatory GM crankshaft relearn procedure.
Estimated Costs for Replacement
The cost to replace the crankshaft position sensor can vary based on who does the work and the brand of part you choose.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Part | $25 - $156 |
| New OEM Part (ACDelco) | $35 - $85 |
| Shop Labor | $110 - $161 |

Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor located on the 2006-2009 Pontiac Torrent?
For the common 3.4L V6 engine, the crankshaft position sensor is located on the back of the engine block, underneath the exhaust manifold. It is a tight spot, but it can be accessed by raising the vehicle.
Can I replace the sensor myself?
Yes, this is a feasible DIY job for someone with moderate mechanical skill. It involves safely raising the vehicle, disconnecting the electrical connector, and removing a single bolt. However, remember that the mandatory "crankshaft relearn" procedure requires a special scan tool that most DIYers do not own. You may need to have a repair shop perform this final step for you.
What is the difference between the camshaft and crankshaft sensors?
They work together but measure different things. The crankshaft sensor tracks the rotation of the crankshaft at the bottom of the engine, while the camshaft sensor tracks the camshaft at the top. On the Torrent 3.4L engine, the two sensors look similar and are located relatively close to each other, so be careful to replace the correct one. The crankshaft sensor is lower down, below the exhaust manifold.
