Camshaft position sensor replacement cost
Cam sensor faults (P0340 and related) cause hard starts, rough running, or no-start — wiring and timing issues can look identical to a bad sensor.
Typical U.S. independent-shop price range
$224–$326 national average for camshaft position sensor replacement.
- Labor: $107–$157
- Parts: $117–$169
- Source: RepairPal — price data as of September 3, 2026. Excludes taxes, fees, diagnostic time, and your location. Related repairs may be needed.
What’s usually included
RepairPal’s average covers camshaft position sensor parts and labor. Connectors, harness sections, and timing repairs are extra. Labor varies widely by engine layout.
Dealer vs independent
Dealers may diagnose with OEM scan tools and quote OEM sensors. Independents can be competitive on parts; insist on signal verification so you don’t pay for a sensor when the timing chain has jumped.
Common upsell red flags
- Sensor replacement without comparing cam vs crank signals
- Timing-chain job pitched from a single cam-sensor code with no correlation data
- Multiple cam sensors replaced “while we’re there” without individual failures
More patterns: spotting upselling.
Questions before you authorize
- Did scope or scan data show a missing/erratic cam signal?
- Could wiring or a tone-wheel/timing issue explain the same code?
- How many labor hours are on the estimate, and why?
- What’s the plan if the code returns after sensor replacement?

DIY vs shop
Easy on some engines, buried on others. Intermittent heat-related failures are common — a shop with a scope may save repeat parts. See DIY vs shop.
