Camshaft position sensor replacement cost is typically $127 to $203 at a shop, based on customer-reported jobs updated November 2, 2026. The part alone can be as little as $30, and the total depends mostly on how hard the sensor is to reach.
Sensor location decides most of the camshaft position sensor replacement cost, so confirm the P0340 code before buying a part. The causes and a GM bulletin that may apply to some 2012 and 2013 vehicles are covered below.
Camshaft Position Sensor Replacement Cost Today
As of November 3, 2026, camshaft position sensor replacement cost typically runs $127 to $203 at a shop, based on customer-reported jobs.
Jerry, a repair-estimate site, lists that range on a page dated November 2, 2026. Because the camshaft position sensor replacement cost figures come from customer-reported jobs, treat them as a practical guide rather than a fixed quote for your car.
A higher benchmark also exists. Mechanicbase, citing RepairPal, gives an average total of $224 to $326 on a page updated October 18, 2026. The gap shows how much shop rates and sensor access can move the bill for camshaft position sensor replacement cost.
The same Jerry page lists seven completed sample jobs with totals from $93.69 to $167.53. A simple job on an easy-to-reach sensor can land below the headline range, while a difficult job can land above it.
The range is wide because it combines parts, labor and local rates in one number. It is not a promise for your car, but it is enough to judge whether a written quote is reasonable.
Parts and Labor Breakdown
In Jerry’s sample jobs, parts ran $28.30 to $87.14 and labor ran $63.90 to $84.31, so the two cost about the same on a typical camshaft position sensor replacement.
| Cost item | Sample range | Time | Source note |
|---|---|---|---|
| Parts | $28.30 to $87.14 | Not applicable | Sensor price in sample jobs |
| Labor | $63.90 to $84.31 | 35 or 45 minutes | Labor in sample jobs |
| Total | $93.69 to $167.53 | Not applicable | Completed jobs, dated November 2, 2026 |
These figures come from completed sample jobs, so they are not a price guarantee. Your quote can differ, and the total still depends on how many parts must come off to reach the sensor.
Labor is the line you can check most easily in any camshaft position sensor replacement quote. Sample labor was 35 or 45 minutes, so a quote with several hours of labor for one sensor deserves a direct question about access.
Ask which part the camshaft position sensor replacement cost quote uses. The sensor price is one of the few line items you can compare directly between shops.
A total near the top of the sample range is not automatically a bad quote. It is worth asking what the extra money pays for, such as a harder location or a higher-priced part.
Why Sensor Location Changes the Price
Access decides the labor time, so camshaft position sensor replacement cost for an easy-to-reach sensor is far lower than for one buried under other parts.
- Easy access: the part costs $30 to $106, and a do-it-yourself owner can finish in 15 to 30 minutes.
- Hard access: professional jobs run $150 to $400 or more and can take one to two hours or longer.
- Crankshaft sensor: a different part with its own price, so do not use crankshaft figures for a camshaft sensor.
Hard-to-reach sensors can also require removing other components first. Jerry’s $150 to $400 or more range for professional work covers that extra time, so camshaft position sensor replacement cost can climb well above the part price.
Ask the shop which parts must come off to reach the sensor. Extra disassembly adds labor, which is why two quotes for the same camshaft position sensor replacement cost can differ widely.
Check the P0340 Code Before You Replace the Sensor
P0340 points to the camshaft position sensor circuit, but the sensor is only one of several possible causes. A related repair cost is covered in timing chain repair price. A meter helps verify the sensor signal, as checking sensor voltage with a multimeter shows.
According to Mechanicbase’s P0340 guide, the code can come from five different sources:
- A failed camshaft position sensor
- Damaged wiring or a damaged connector
- A damaged or misaligned sensor target, such as a timing rotor or trigger wheel
- A mechanical timing problem, such as a timing chain or belt that has jumped, stretched or been installed wrongly
- An engine computer fault, which the guide calls uncommon
Because P0340 names a circuit rather than one broken part, a code alone does not settle whether camshaft position sensor replacement is needed. KBB also lists camshaft position sensor replacement among common repairs for P0340, but it gives no dollar figure.
Expect the shop to charge a diagnostic fee before any camshaft position sensor replacement starts. Many shops charge $120 to $200, and Jerry notes that the fee can be applied to the repair if you approve the job.
Before you pay for a part, ask the shop to show the code and the test steps that rule out wiring, the sensor target and timing. Buying a part before those checks can waste money on camshaft position sensor replacement cost without fixing the fault.
Shop, Dealer and DIY Options
A do-it-yourself owner pays only for the part, so camshaft position sensor replacement cost is lowest on an easy-to-reach sensor, while a shop adds labor on top. Another sensor job priced in oxygen sensor replacement cost makes a useful comparison.
This guide does not give a verified hourly shop rate. Compare written quotes from two or three shops that list parts and labor separately, so you can judge the cost for your car.
- Do it yourself: the part only, $30 to $106 for an easy-to-reach sensor, plus your time.
- Independent shop: parts, labor and any diagnostic fee should appear as separate lines.
- Dealer: the same job with its own labor time, so ask which labor time the quote uses.
Ask whether the quote lists the labor hours, whether the diagnostic fee is credited, and whether the sensor is new or remanufactured. Those three answers explain most of the difference in camshaft position sensor replacement cost between two quotes.
DIY is a poor fit when the sensor is hard to reach or when the code returns after camshaft position sensor replacement. In that case the cause may be wiring, the sensor target or timing, and a shop can test those before you buy more parts.
Check for Known GM Service Bulletins
GM bulletin PIP5099A, dated March 2013, covers an intermittent P0340 on certain 2012 and 2013 vehicles built in September or October 2012.
The GM bulletin PIP5099A is hosted on NHTSA’s site and was written for technicians. It names these vehicles:
- 2012 to 2013 Cadillac Escalade and CTS-V
- 2012 to 2013 Chevrolet Camaro, Caprice, Corvette, Avalanche, Silverado, Suburban, Tahoe and Express
- 2012 to 2013 GMC Sierra, Yukon and Savana
The bulletin covers engines in the 4.8, 5.3, 6.0 and 6.2 liter families and vehicles built in September or October 2012. If standard diagnostics does not fix the intermittent code, it recommends replacing the cam position sensor, with published labor operation J4350 for camshaft position sensor replacement cost.
This is a technician bulletin, not a recall, and it does not make camshaft position sensor replacement cost free. Check your VIN with a GM dealer before assuming the bulletin applies to your car. If your vehicle is outside these models, the bulletin does not apply, and the same P0340 diagnosis steps still hold.
Frequently Asked Questions
How much does camshaft position sensor replacement cost?
Customer-reported jobs put it at $127 to $203 as of November 2, 2026. Sample completed jobs ranged from $93.69 to $167.53. Your vehicle and the sensor’s location decide where your bill lands.
Can I replace a camshaft position sensor myself?
Often yes, if the sensor is easy to reach. The part costs about $30 to $106 and the job can take 15 to 30 minutes. Hard-to-reach sensors can take one to two hours or more, so a shop may be the better choice.
How long does the job take?
Jerry lists 15 to 30 minutes for a do-it-yourself job on an easy-to-reach sensor, and one to two hours or more for professional work on a hard-access sensor. Access, not the sensor itself, sets most of the time.
Does P0340 always mean the camshaft sensor is bad?
No. The code can come from wiring, a damaged sensor target, a timing problem, or a rare computer fault. Confirm the cause with a scan and a wiring check before you buy a part.
Is there a GM bulletin for this code?
Yes, for some vehicles. PIP5099A covers listed 2012 and 2013 GM models built in September or October 2012. It is a technician bulletin, not a recall, so check your VIN with a dealer before assuming it applies.
Is the diagnostic fee worth paying?
Many shops charge $120 to $200 to diagnose a code, which adds to camshaft position sensor replacement cost, and some apply that fee to the repair if you approve the job. Ask about the fee before you agree to the diagnosis, so the total is clear.
Before you approve any camshaft position sensor job, confirm the code, ask for parts and labor on separate lines, and check whether the diagnostic fee is applied to the repair. The quote for your car is the number that matters for camshaft position sensor replacement cost, not an average. Use the ranges in this guide to judge whether that quote is reasonable.
