Saturn Vue 2002-2010 Engine Crankshaft Position Sensor Replacement Guide
Fix your Vue's stalling or no-start problem by choosing the right crankshaft sensor.
- A failing sensor commonly causes stalling when hot and no-start conditions.
- Replacement is much harder on V6 engines than on 4-cylinder models.
- A 'relearn' procedure with a scan tool is often required after installation.
- For reliability, choose premium brands like ACDelco or Delphi.
Understanding Crankshaft Sensor Failure in the Saturn Vue
A failing crankshaft position sensor is a common reason for a Saturn Vue to stall, especially when the engine gets hot, or refuse to start at all. This sensor provides the engine's computer with essential information. When it fails, the computer gets confused, leading to significant and potentially dangerous driving issues. Because this part is so important for engine operation, it's a repair you shouldn't put off.
Symptoms of a Bad Crankshaft Position Sensor
If your Vue's crankshaft sensor is failing, you will likely notice one or more distinct symptoms. The most common and serious is the engine stalling without warning, which can be a major safety hazard if it happens while driving. You might also find the engine cranks but won't start, or it takes a long time to finally fire up. A lit Check Engine Light is another frequent sign, often with code P0335.

The 2002-2010 Saturn Vue came with different engines, most commonly the 2.2L 4-cylinder and various V6 options (3.0L, 3.5L, 3.6L). The location of the crankshaft sensor and the difficulty of replacement vary significantly between these engines. The 4-cylinder sensor is generally easier to access than the V6 sensors, which can be buried and require removing other parts like the starter or even the transfer case on AWD models. Always confirm your engine size before ordering a part or starting the repair.
Choosing the Right Aftermarket Crankshaft Sensor
When replacing this sensor, you have a choice between OEM-affiliated brands and a wide range of aftermarket options. For a critical sensor like this, quality matters.
- Premium Brands (ACDelco, Delphi, Bosch): These brands are often the original equipment (OE) suppliers to General Motors. Choosing an ACDelco or Delphi sensor is the closest you can get to the original part's quality and reliability without paying dealer prices. They are widely considered the most reliable choice for a long-lasting repair.
- Quality Aftermarket (Standard Ignition, NGK/NTK, Beck Arnley, Dorman): These brands are well-known in the aftermarket and generally offer good quality. Dorman is known for making direct-fit replacements, and NTK (a division of NGK) is a respected sensor manufacturer. These can be a good balance of price and quality.
- Economy Brands: While the lower price is tempting, budget-friendly sensors have a higher risk of failing early. This can mean doing the entire repair job a second time. For a part that can cause your engine to stall in traffic, it's often worth spending a little more for a part from a more reputable manufacturer.
Cost to Replace a Saturn Vue Crankshaft Position Sensor
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Part | $16 - $156 |
| Shop Labor | $125 - $350 |
| Total Estimated Cost | $141 - $506 |
Cost estimates are for the part and labor and can vary based on your location, vehicle engine, and the specific repair shop. The labor cost varies widely due to the difference in replacement difficulty between engine types.
Pro Tip: Check the Connector
The plastic electrical connector and wiring for the sensor can become brittle and damaged from engine heat. Before replacing the sensor, inspect the connector and wiring harness for any signs of cracking, melting, or corrosion. A bad connection can mimic the symptoms of a failed sensor. 🎬 Watch this guide to diagnose wiring issues if codes persist. Connectors are available as a separate part if needed.
Frequently Asked Questions
Why does my Vue stall when it's hot but restart after it cools down?
This is a classic symptom of a failing crankshaft position sensor. The electronic components inside the sensor can fail when they reach a certain temperature, cutting the signal to the computer and stalling the engine. After the sensor cools down, it may start working again temporarily.
Is there a recall on the Saturn Vue for the crankshaft position sensor?
No, there are no specific safety recalls issued by the NHTSA for the crankshaft position sensor on the 2002-2010 Saturn Vue. There were recalls for other issues on these vehicles, such as ignition switches and door latches, but not the sensor itself.
Do I need a special tool to perform a 'relearn' procedure after replacement?
Yes, for many Saturn Vue models, a Crankshaft Position System Variation Learn procedure is required after replacing the sensor. This procedure uses a compatible scan tool to calibrate the new sensor with the engine computer. Failing to do this may result in a continued Check Engine Light or poor engine performance.
Where is the crankshaft position sensor located on my Saturn Vue?
The location depends on your engine. On the 2.2L Ecotec 4-cylinder, it's on the lower front of the engine, behind the starter. 🎬 Watch this walkthrough for locating the sensor on 4-cylinder models. On V6 models (like the 3.5L or 3.6L), it is often located behind a heat shield near the catalytic converter or requires removal of the transfer case on AWD models to access.
