12 Key Signs of bad camshaft position sensor symptoms

Discussion Topic: 12 Key Signs of bad camshaft position sensor symptoms

Your car is equipped with many special sensors, and among them is the camshaft position sensor (CPS). This sensor is built to last as long as your car does, but sometimes, it might not work properly due to wear and tear over time.

When the camshaft position sensor starts failing, your car will show certain warning signs that shouldn’t be ignored.

Common reasons for camshaft position sensor failure.

Every part of your car, including the camshaft position sensor, can sometimes stop working. This usually happens because of regular use over time or from accidents.

12 Key Signs of bad camshaft position sensor symptoms

Having trouble with your car starting or noticing it’s not running as smoothly as it should? It could be an issue with the camshaft position sensor, a crucial part of your car’s engine.

Camshaft Position Sensor Symptoms

Here’s an easy-to-understand breakdown of the signs indicating it might be failing:

1. Trouble Starting Your Car: If turning the key results in your engine cranking without starting, it’s possible that the camshaft position sensor isn’t working correctly. This sensor plays a big role in controlling the engine’s spark and fuel delivery, both essential for getting your car started.

2. Longer Starting Times: Sometimes, your car might take a few more attempts to start than usual. This happens because the sensor isn’t sending the right information needed for the engine to ignite properly.

3. Poor Gas Mileage: If you’re finding yourself at the gas station more often, it could be due to inefficient fuel use caused by incorrect signals from the faulty sensor, leading to poor fuel combustion.

4. Engine Stalling: Your car unexpectedly stalling might be the result of not getting the right amount of fuel from the fuel injectors, again stemming from issues with the camshaft position sensor.

5. Rough Engine Idling: A rough or irregular engine rhythm while idling can indicate the sensor’s failure, making this common symptom hard to ignore.

6. Hesitation During Acceleration: If your car hesitates or stumbles when you step on the gas, it’s a sign of trouble in the timing of fuel delivery and spark, possibly due to a bad sensor.

7. Failing Emissions Tests: A car that doesn’t pass emissions tests likely isn’t burning fuel efficiently, a problem often associated with a faulty camshaft position sensor.

8. Gas Smell: A noticeable gas odor could point to unburned fuel exiting through the exhaust, indicating the engine isn’t firing properly.

9. Car Doesn’t Start: Over time, a failing sensor can completely prevent your car from starting due to the lack of a signal to the engine control module.

10. Engine Misfires: An engine that misfires, or doesn’t run smoothly, could be experiencing problems due to a faulty sensor.

11. Transmission Issues: Odd shifting patterns or your car stuck in a low gear (“limp mode”) can also be a symptom of sensor-related problems.

12. Check Engine Light: If you see this light on your dashboard, it could be your car’s way of telling you something’s wrong with the camshaft position sensor among other possible issues. If that light flashes, you should stop driving and call for assistance.

Need to Change Your Car’s Camshaft Sensor? Here’s What to Know

Is your car acting up and you suspect it’s the camshaft sensor? It’s time to get it checked! Fixing it sooner rather than later can help you avoid more issues and big repair costs.
Getting a new camshaft sensor is straightforward and won’t break the bank. Taking care of it now could save you money down the line.

What Happens if You Keep Driving?

Technically, your car might still run with a faulty sensor, but it’s not a good idea. If you keep driving, you could end up damaging other parts of your car, leading to more expensive repairs. Plus, there’s a chance your car might stall while you’re driving, which isn’t safe for you, your passengers, or other people on the road.

  1. Can a bad crankshaft position sensor prevent an engine from starting or only cause it to stall while running? I have a 2008 Subaru and I’m experiencing intermittent starting issues – sometimes the engine turns over but doesn’t start fully, while other times it starts without any problem. Today, the engine stalled while I was driving. The auto repair shop suggested that a faulty crankshaft part could be responsible for both the engine cutting off and the starting issues. Could this be the reason for my car’s occasional failure to start?
