On a 2012 Chevy Equinox, replacing the crankshaft position sensor generally costs about $150 to $350, depending on the engine, part choices, and local labor rates.
What a crankshaft position sensor does and why it fails
The crankshaft position sensor (CKP) provides the engine computer with real-time data about the crank’s position and speed. When the sensor or its wiring starts to fail, symptoms can include hard starting, stalling, misfires, a no-start condition, or a Check Engine light. Causes of failure range from age and heat exposure to wiring damage or a faulty connector. Replacement is a common maintenance item, though access and complexity can vary by engine configuration in the Equinox.
Cost breakdown
Below is a breakdown of the typical costs you can expect when replacing the CKP sensor on a 2012 Equinox.
- Parts: The CKP sensor itself is usually $20–$95. You may also need a gasket or O-ring ($5–$15) and occasionally a mounting bolt or seal.
- Labor: Labor time is typically 0.8–2.0 hours, depending on engine layout and access. Labor rates often range from $75–$125 per hour, though some regions charge more.
- Diagnostics and programming: A diagnostic check is sometimes included with the repair, but some shops charge a separate diagnostic fee ($0–$100). Most 2012 Equinox CKP replacements do not require programming, but a quick relearn or reset may be needed in rare cases.
In practice, most owners see total costs fall in the $150–$350 range, with higher figures more likely in areas with elevated labor rates or if additional work is required.
DIY vs professional replacement
Replacing the CKP sensor can be a feasible DIY task for a mechanically skilled person with basic hand tools and a torque wrench. Doing it yourself usually reduces cost to the price of parts, which can be as low as $20–$95 for the sensor plus any gaskets or seals. However, some engine configurations on the Equinox place the sensor in a hard-to-reach spot, making professional replacement safer and faster.
Pros of a DIY approach
Lower overall cost, hands-on troubleshooting, and immediate completion if you have the tools and room to work.
Pros of professional service
Guaranteed installation, proper torque on fasteners, potential avoidance of wiring damage, and a diagnostic check to confirm there are no related codes or issues.
What to know before you replace
Before committing to a replacement, confirm the symptoms match a CKP problem and check for related trouble codes (such as P0335, P0336, or P0339, depending on the circuit). In some cases, other ignition or fuel system issues can produce similar symptoms. Getting a reliable diagnosis helps ensure you’re not paying for an unnecessary part replacement. If you choose to have a shop perform the work, ask for a written estimate that itemizes parts, labor, and any diagnostic fees.
Summary
The crankshaft position sensor replacement on a 2012 Chevy Equinox typically costs between $150 and $350, with most repairs landing around $200–$300 in many regions. Parts are usually inexpensive, while labor is the main driver of price, especially in high-cost areas. DIY replacements can reduce costs, but professional service provides safety and diagnostic assurance. Always verify symptoms, codes, and the necessity of any re-learn procedure with your technician.
