Default CMP Sensor Replacement

Quick question. My check engine light comes on after re-starting the car while it's hot. The code says it's a bad sonsor. If the sensor is bad will the cars still run and run fine because it does.

Default It can seem like it is running fine, but obviously you need a new part. =-)

I've had sensors go bad and the car seems fine. The coolant temp sensor is a good example, car seems to run fine but CEL was still on. I switched out the sensor and the car seems the same but gets better MPG.

Default Also, check the wiring to the sensor first...

you need to fix the problem and not try to drive that car as if the problem does not exist. I can't say if you would damage things or not.
