The replacement typically costs about $150 to $350, including parts and labor. Exact quotes vary by shop, region, and whether you choose an aftermarket or Honda OEM sensor.
In more detail, a failing crankshaft position sensor can trigger symptoms such as a check engine light, stalling, or difficulty starting. The 2012 Honda Civic (9th generation) uses a single crankshaft position sensor located near the crankshaft area, and replacement is usually a straightforward job for a trained technician. Prices reflect sensor type, labor rates, and how accessible the sensor is in your engine bay.
What is a crankshaft position sensor and why it fails
Symptoms of a failing sensor
The crankshaft position sensor (CPS) monitors the crank’s position and rotation speed. When it fails, the engine may stall, have trouble starting, run poorly, or trigger codes such as P0335. Common causes include wiring damage, corroded connectors, sensor wear, oil leaks, or a faulty ignition system that stresses the sensor.
Replacement basics
Replacing the CPS involves locating the sensor near the crankshaft, disconnecting the electrical connector, removing the mounting bolt, and installing a new sensor with proper torque. Reassembly, code clearing, and a test drive complete the job. In most cases, no additional major components must be replaced unless there are related wiring issues or timing-related wear.
Cost overview
Below is a quick breakdown of typical costs you can expect for a 2012 Honda Civic.
- Parts: Aftermarket sensors generally cost about $25–$120; Honda OEM sensors commonly run around $60–$180, depending on supplier and whether it’s a dealer part.
- Labor: Most shops bill 0.5–1.5 hours for this replacement, at roughly $75–$125 per hour depending on your region and shop type.
- Total: In practice, most customers see a combined price in the range of about $150–$350, with dealer quotes sometimes higher and independent shops typically on the lower end.
Prices can vary based on where you service the vehicle, whether diagnostic fees are charged, and if multiple components need replacement due to related wiring or harness damage.
Factors that affect price
Several factors can push the final bill higher or lower than the baseline estimate.
- Location and shop type: Dealerships tend to be more expensive than independent repair shops or chain auto centers.
- Sensor type: OEM Honda parts typically cost more than aftermarket equivalents, though some owners prefer OEM for perceived longevity or warranty reasons.
- Accessibility: If the sensor is hard to reach or requires removing additional components, labor time increases.
- Additional issues: Wiring harness damage, corroded connectors, or unrelated engine codes may require extra labor or parts.
- Warranty and diagnostic fees: Some shops include a diagnostic fee in the estimate or offer warranties on parts and labor, which can affect total cost.
To avoid surprises, request a detailed, written estimate that separates parts, labor, and any diagnostic or shop fees.
DIY vs professional replacement
Choosing between doing it yourself and hiring a pro depends on your comfort level, tools, and whether you want a warranty on the work.
- Pros of DIY: Lower upfront cost, hands-on learning, and no labor markup if you already own tools.
- Cons of DIY: Risk of misdiagnosis, potential wiring damage, and no professional warranty on the workmanship.
- Pros of professional replacement: Experienced diagnosis, proper torque specs and sensor seating, and parts/labor warranties.
- Cons of professional replacement: Higher overall cost due to labor and shop overhead.
If you’re uncertain about your mechanical skills, or if other electrical codes are involved, a professional replacement is generally the safer option.
How to get an exact quote
To receive an accurate price, contact local shops with your Civic’s details and the symptoms you’ve observed.
- Provide year, make, model, and engine size (2012 Honda Civic 1.8L is common for this model).
- Describe symptoms (stalling, no-start, check engine light) and any codes if you’ve read them (for example, P0335).
- Ask for a parts-included price and whether the quote covers OEM vs aftermarket sensors.
- Request a breakdown of parts vs. labor and whether diagnostic time is charged separately.
- Inquire about the warranty on parts and labor if you choose to proceed.
Getting multiple quotes can help you gauge market prices and identify the best value for your situation.
Summary
For a 2012 Honda Civic, replacing the crankshaft position sensor typically lands in the $150–$350 range, with OEM parts generally at the higher end and labor costs varying by region. Symptoms of failure include engine stalling, no-start conditions, and a check engine light. Accessibility of the sensor and any related wiring issues drive final pricing. Whether you DIY or hire a pro, obtain a clear, itemized estimate and consider warranty options to protect your investment. If in doubt, a certified mechanic can confirm diagnosis and ensure the replacement is done correctly.
