Crankshaft Position Sensor Replacement Cost
Quick answer
Crankshaft-position-sensor replacement commonly totals about $180–$500 in the US. Easy-access sensors can cost less; sensors behind a starter, transmission area or timing cover can cost more. Diagnose wiring and signal first.
The sensor is often affordable, but location controls labor. A connector repair may cost less than replacement, while difficult access can dominate the bill.
Intermittent hot stalls and a zero-RPM reading while cranking support a CKP signal problem, but they do not identify whether the sensor, harness or reluctor is responsible.
Typical price ranges
| Scenario | Typical range (US) |
|---|---|
| Diagnosis | $100–$220 |
| Easy-access sensor | $180–$320 |
| Difficult-access sensor | $300–$500+ |

What moves the price
-
Sensor location
Access may require removing shields, a starter or other components.
-
Wiring damage
Oil, heat and chafing can turn a parts job into harness repair.
-
Calibration procedure
Some vehicles require a crankshaft-position variation relearn after repair.
How to pay less (without getting burned)
- Ask whether RPM was present during cranking.
- Use an OEM-quality sensor; poor signal quality can cause repeat failures.
- Confirm whether the quote includes a relearn.
Frequently asked questions
- Can wiring be the real problem?
- Yes. Low-input and intermittent codes frequently come from a short, open, loose terminal or heat-damaged harness.
- Will the engine run with a bad crank sensor?
- It may stall, crank without starting or fail only when hot, depending on the vehicle and failure mode.
- Does every replacement need a relearn?
- No. Requirements vary by manufacturer and model; follow the service information for the vehicle.
