If this part was recalled, is the repair free?
Federal law (49 U.S.C. 30120) requires a maker to fix a recalled defect without charge for cars first bought within 15 calendar years (tires within 5), and NHTSA lists 1 recall campaigns for parts matched to a camshaft position sensor replacement since model year 2015, covering about 42,231 vehicles.
| Rule or count | What it says |
|---|---|
| Age limits | The free-remedy duty does not apply to a car first bought more than 15 calendar years, or a tire first bought more than 5 calendar years, before the recall notice. |
| Failure to fix | A repair not done adequately within 60 days of presentation is prima facie evidence of failure to repair within a reasonable time; the maker must then replace the vehicle or refund the purchase price less depreciation. |
| Free remedy | A maker must fix a recall defect without charge. |
| NHTSA recalls matched to a camshaft position sensor replacement since model year 2015 | 1 recall campaigns covering about 42,231 vehicles |

A bulletin is a repair procedure a maker sends its dealers, not a safety defect: if your maker is listed, ask the dealer whether one covers your car and quote its number.

What do owners say?
3 complaints quoted word for word, each with its NHTSA number.
Vehicle developed a check engine light and camshaft sensor fault at approximately 48,000 miles.
My camshaft sensors went bad at 77k miles had it towed to auto repair.
The independent service center stated they could reproduce the problem and that it was the camshaft sensor which I had replaced for $400 but the problem continued not even an hour after I picked up the vehicle.
Check your car
Our calculator's default estimate is $205–$350, parts plus labor, for a chain shop at $120 an hour on an engine where the sensor is easy to reach. A buried rear-bank sensor on a DOHC engine raises that to $325–$710.
What does the estimate cover and leave out?
It leaves out a diagnostic fee, taxes and any other part the shop finds while it is in there. Ask the shop whether the quote includes a scan of the stored codes and whether the sensor is the maker's part or an aftermarket one.
How much do engine access and shop type change it?
Access to the sensor moves the price most, because it sets the labor hours. Shop type moves it less. These are the calculator's ranges.
| Setting | Estimate |
|---|---|
| Default: easy-access engine, chain shop | $205–$350 |
| DOHC engine, accessible sensors | $245–$490 |
| DOHC engine, buried rear bank | $325–$710 |
| Independent shop, easy-access engine | $190–$320 |
| Dealership, easy-access engine | $246–$433 |
What should I ask the shop?
Ask how many sensors the quote replaces, because some engines have more than one. Ask how much labor time is quoted, and compare it with the access row above. Ask what code the scan showed, and whether the check-engine light was cleared and rechecked after the repair.
Frequently asked questions
Is a higher quote always a sign of a rip-off?
No. A buried rear-bank sensor needs more labor, so check the quoted hours against the table before deciding.

What is our own estimate
The price range comes from our calculator's formula. Its parts prices, labor hours per job and shop-rate tiers are CalcScrape estimates, not a published price dataset. Checked against RepairPal's range ($224–$326) on 2026-10-04: our default's midpoint is 1% above the middle of that range. Methodology
