Knowing the camshaft position sensor replacement cost by vehicle make and model saves you from getting overcharged at the shop or from putting off a repair that's more affordable than you think. This sensor is a small part, but when it fails, your engine can stall, misfire, or refuse to start altogether. The tricky part is that the cost varies wildly depending on what you drive. A replacement on a Honda Civic might run you under $150 total, while the same job on a BMW could exceed $500. This article breaks down real costs by popular vehicles so you can budget smart and avoid surprises.

What Does a Camshaft Position Sensor Actually Do?

The camshaft position sensor (CMP sensor) monitors the position and speed of your camshaft and sends that data to the engine control module (ECM). The ECM uses this information to control fuel injection timing and ignition timing. Without a working sensor, your engine doesn't know when to fire each cylinder. That leads to rough idling, poor fuel economy, stalling, or a complete no-start condition. If you've seen a P0340 trouble code or are dealing with a no-start situation, the camshaft position sensor is one of the first things to check.

How Much Does Camshaft Position Sensor Replacement Cost?

Nationally, the average total cost for camshaft position sensor replacement ranges from $75 to $350. That breaks down into two parts:

Parts: $15 to $120, depending on the vehicle and whether you use OEM or aftermarket
Labor: $60 to $250, depending on how hard the sensor is to access

Some sensors sit right on top of the engine and take 20 minutes to swap. Others are buried under intake manifolds or timing covers, which drives labor time up fast.

Camshaft Position Sensor Replacement Cost by Vehicle Make and Model

Honda

Honda Civic (2006–2015): $75–$160 total. The sensor is usually easy to reach, which keeps labor low.
Honda Accord (2008–2017): $90–$180 total. Similar layout to the Civic; most shops charge under an hour of labor.
Honda CR-V (2007–2016): $85–$175 total. Straightforward replacement in most model years.

Toyota

Toyota Camry (2007–2017): $80–$170 total. The 2.5L engine makes sensor access relatively simple.
Toyota Corolla (2009–2019): $70–$150 total. One of the cheaper replacements you'll find.
Toyota RAV4 (2006–2018): $90–$200 total. The V6 models cost slightly more due to tighter engine bays.

Ford

Ford F-150 (2004–2014): $90–$220 total. The 5.4L Triton engine can be more labor-intensive.
Ford Escape (2008–2012): $100–$210 total. Some model years require partial intake removal.
Ford Focus (2012–2018): $80–$170 total. Fairly accessible sensor location.

Chevrolet

Chevrolet Silverado 1500 (2007–2013): $100–$250 total. The V8 engines have two cam sensors (bank 1 and bank 2), so costs can double if both need replacement.
Chevrolet Malibu (2008–2015): $85–$180 total.
Chevrolet Equinox (2010–2017): $90–$200 total.

Nissan

Nissan Altima (2007–2018): $80–$190 total. The 2.5L is easy; the 3.5L V6 costs a bit more.
Nissan Rogue (2008–2015): $90–$180 total.
Nissan Maxima (2009–2016): $100–$220 total. The V6 layout adds labor time.

BMW

BMW 3 Series (E90/F30, 2006–2018): $180–$450 total. German engineering means tighter spaces, and OEM parts cost more. Some models have multiple cam sensors.
BMW X3/X5 (2007–2016): $200–$500 total. Expect higher labor charges due to engine bay complexity.

Mercedes-Benz

Mercedes C-Class (2008–2015): $200–$480 total. Parts are pricier, and specialized labor adds up.
Mercedes E-Class (2010–2016): $220–$500 total.

Hyundai / Kia

Hyundai Sonata (2011–2019): $75–$170 total. Very budget-friendly repair.
Hyundai Elantra (2011–2020): $70–$160 total.
Kia Optima (2011–2019): $80–$180 total.
Kia Sorento (2011–2015): $90–$200 total.

Jeep

Jeep Wrangler (2007–2018): $100–$230 total. The 3.6L Pentastar V6 can be a tight fit.
Jeep Grand Cherokee (2005–2015): $110–$250 total.

Dodge

Dodge RAM 1500 (2009–2018): $100–$260 total. Hemi engines have multiple cam sensors.
Dodge Charger/Challenger (2011–2018): $110–$280 total.

Why Does the Cost Vary So Much Between Vehicles?

Three factors drive the price difference:

Sensor location. On some engines, the CMP sensor sits right on the cylinder head with one bolt and an electrical connector. On others, it's behind the timing cover or under the intake manifold, requiring an hour or more of disassembly.
OEM vs. aftermarket parts. An OEM BMW sensor can cost $80–$120, while an aftermarket equivalent might be $25–$50. Quality varies, though more on that below.
Number of sensors. Many V6 and V8 engines have two camshaft position sensors (one per bank). If you're getting symptoms on both sides, expect to pay for two sensors and possibly double the labor.

Can I Replace the Camshaft Position Sensor Myself?

On many vehicles, yes. If the sensor is accessible without major disassembly, the job takes 15–30 minutes with basic hand tools. You'll typically need a 10mm bolt and to unplug an electrical connector. Before you start, you can test the sensor with a multimeter to confirm it's actually bad before replacing it.

That said, some vehicles make this job miserable. If the sensor sits behind the timing cover or requires removing the intake manifold, it's usually worth paying a shop. You don't want to start the job in your driveway on a Saturday and realize you're in over your head.

OEM or Aftermarket: Which Sensor Should You Buy?

This is where people often waste money or create new problems.

OEM (Original Equipment Manufacturer) sensors are made to the exact spec of your vehicle. They cost more but tend to last longer and avoid fitment issues.
Aftermarket sensors range from decent (brands like Delphi, Standard Motor Products, or SMP BWD) to junk (unbranded sensors on marketplaces for $8).

Common mistake: Buying the cheapest sensor available to save $20, then having to replace it again in 6 months when it throws the same code. A mid-range aftermarket sensor from a known brand is usually the sweet spot if you don't want to pay OEM prices.

What Happens If I Ignore a Bad Camshaft Position Sensor?

A failing CMP sensor won't fix itself. You might notice loss of power while driving or sudden stalling in traffic, which is a safety issue. Other risks include:

Engine won't start or takes multiple cranks
Rough idle and misfires that can damage your catalytic converter over time
Poor fuel economy as the ECM can't optimize timing
Failed emissions test

Ignoring it doesn't save money it usually turns a $100–$200 fix into a bigger repair.

How to Save Money on Camshaft Position Sensor Replacement

A few practical tips:

Get the diagnostic code read first. Auto parts stores will often scan your codes for free. Confirm the issue before paying a shop for diagnosis.
Compare shop quotes. Call at least two independent shops and a dealership. Independent shops typically charge $20–$50 less per hour in labor.
Buy the part yourself (carefully). Some shops let you bring your own part, though they may not warranty the labor. Know your vehicle's engine code to get the right sensor.
Check if there's a TSB or recall. Some vehicles have known cam sensor issues covered under extended warranty or service campaigns. Check with your dealer using your VIN.
Replace both sensors on V-engines. If one cam sensor goes on a V6 or V8, the other is usually not far behind. Paying the labor once is cheaper than coming back in 3 months.

Quick Checklist Before You Book the Repair

Use this checklist to make sure you're making a smart, informed decision:

✅ Confirm the trouble code (P0340, P0341, P0344, P0345, P0349, etc.) with an OBD-II scanner
✅ Identify your exact engine size and year sensor fitment varies even within the same model
✅ Research whether your sensor is easy to access or buried under other components
✅ Compare OEM and quality aftermarket part prices for your specific vehicle
✅ Get at least two quotes from local shops before committing
✅ Ask if both sensors should be replaced (for V6/V8 engines)
✅ Check for any open recalls or TSBs related to your camshaft sensor
✅ If replacing yourself, test the old sensor with a multimeter first to confirm failure

Taking 10 minutes to do this homework can save you $50–$200 on the repair and make sure the problem actually gets fixed the first time.
