What happens if the CKP sensor is bad?
If the CKP or CMP sensor is bad, you’ll get no reading. Since this type of sensor only has two wires and no power supply, testing them is not that hard: One of the two wires is the signal wire that sends the signal to the fuel injection computer of ignition module.
Can a crank and cam sensor be replaced?
I replaced both the cam and crank sensor and car still will not start but if I unplug the crank sensor it starts up and runs like crap. I can not figure out what to do next. My car has 91000 miles. My car has an automatic transmission. You should check to see if your vehicle has jumped timing.
What does the CKP stand for in a car?
Both (CKP)- (CMP) position sensors are part of your car’s electronic fuel injection and ignition system. In the old days, if you had fuel, spark and were close to correct in timing, your engine would run.
What can cause a CMP sensor to fail?
There are a few things that can cause these (CKP)- (CMP) sensors to fail: 1 Damage 2 Debris 3 Faulty circuitry More …
What does the CKP sensor tell the fuel injection computer?
More specifically, the (CKP) Sensor produces a signal that tells the Fuel Injection Computer or the Ignition Control Module; the exact position of the cylinder pistons as they come up or go down in the compression cycle.
What happens if the crankshaft position sensor is not creating a signal?
And so, if the Crankshaft Position Sensor isn’t creating a Signal, then the measurable/testable effects of this condition are but not limited to: The Triggering Device (whether it’s the Ignition Control Module or the F.I. Computer) will not produce a Switching Signal to the Ignition Coil. No Spark coming out of the Ignition Coil or Coils.
Why does the cam sensor not send a signal to the ignition coil?
Since, the Ignition Control Module really doesn’t send a physical signal (like the Crank or Cam Sensor does to the Switching Device) to the Ignition Coil (s). Why? Well, because the term ‘Switching Signal’ is just a descriptive name for the turning on and off of the primary current passing thru’ the Ignition Coil.
How does a crankshaft camshaft position sensor work?
Since this type of Sensor only has two wires and no Power Supply, testing them is not that hard: One of the two wires is the Signal wire. Consequently, Sending the Signal to the Fuel Injection Computer or Ignition Module. The other wire acts as a Ground return.
