How does the camshaft position sensor work on a jeep?
Camshaft position sensor determines which cylinder is firing. Then it uses that information to sync the injectors with the ignition. The CPS is one of two sensors that if they fail, your Jeep will not fire the spark plugs or cycle the fuel injectors.
What to do if your camshaft position sensor is bad?
If you have a two-wire, magnetic-type CMP sensor, set your multimeter to “AC volts.” Have an assistant turn the ignition key on without starting the engine. Check for the presence of power flowing through the circuit. Touch one of your probes to ground (any metal part on the engine) and the other probe to each one of the sensor wires.
How to change crankshaft sensor on Jeep Wrangler?
If you get a reading of low resistance, replace the sensor. On all 2.5L & 4.0L engines (except YJ models that come with the 4.0/automatic combination) there are 2 bolts and the plug to deal with. Unplug the harness. Just take out those 2 bolts and pull the sensor out of the bell housing.

How can I test my crankshaft position sensor?
Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.

How to install a cam sensor on a jeep?
Pull all the spark plugs out so she rolls over easy. Put your finger into #1 cylinder or use a compression tester with a removable head (so all you have is the hose threaded into the #1 spark plug hole). Turn the engine over using a socket on the crank or alternator if the alternator is easier to reach.
How can I test my camshaft position sensor?
Test the sensor its self. To test the CPS you will need an analog (old school with the sweeping needle) voltmeter and small paper clips. Using the small paper clips, straighten and insert them into the backside of the distributor wiring harness connector.
What are the symptoms of a bad camshaft position sensor?
Symptoms of a Bad or Failing Camshaft Position Sensor. $79.99 – $89.99. Average rating from 4,829 customers who received a Check Engine Light is on Inspection. The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM).
When does the Check Engine light come on?
Check Engine Light comes on. The Check Engine Light will come on once the camshaft position sensor starts to go bad. Since this light can come on for many different reasons, it is best to have the vehicle thoroughly inspected by a professional.
What is the camshaft sensor code on a Jeep Grand Cherokee?
My 2011 Grand Cherokee V6 has a check engine light with the Camshaft Position Sensor code (P0340). The car goes into limp mode now when the light comes on, but it has cleared on its own before.

How to replace crankshaft position sensor on Jeep Grand Cherokee?
This is going to be a how to on replacing the crankshaft position sensor on the 4.0L motor in the Grand Cherokee. This is by no means the ONLY way or “correct” way to replace the sensor. This is only the way I changed the sensor.
Is there a way to relearn the cam position sensor?
There is a Cam Position Relearn procedure that can be done with the dealer proprietary tool or some of the expensive aftermarket independent tools. But that procedure is not for replacing the cam position sensor, its for when you take the timing chain/belt and cam apart, like during a head change.
Where is the sync pulse generator located on a Jeep Cherokee?
In the case of the Jeep 4.0L engine: the CAMshaft position sensor is also called the ‘sync pulse generator’ (or stator) and can be found in the “distributor” while the CRANKshaft position sensor is located on the transmission bellhousing. (* See bottom of page.)

Step 1 Locate the crankshaft position sensor on the driver side of the bell housing, about half way down. It is secured with two 7/16-inch bolts and has a cable that runs up and onto the engine. Remove the two 7/16-inch bolts from the bracket holding the CPS.
What happens when a camshaft position sensor goes bad?
One of the most common problems which occur due to a bad camshaft position sensor is that the engine’s performance reduces drastically. You will notice frequent stalling, idling and drop in RPM. The fuel efficiency will drop as well.
The engine may stall intermittently. You may notice poor engine performance including irregular acceleration, misfiring, hard starting, or surging. On some car models, a failed CMP sensor will prevent the ignition from making a spark, so that the engine won’t start at all.
Where is the camshaft position sensor located on a Jeep Grand Cherokee?
1993, 1994, 1995 4.0L Jeep Grand Cherokee. The camshaft position sensor (located inside the ignition distributor) gets power from the powertrain control module (PCM) thru’ the WHT/BLK (white with black stripe) wire. This power is in the form of 8 Volts DC.
What kind of DC does the camshaft position sensor use?
This power is in the form of 8 Volts DC. The WHT/BLK wire also feeds the crankshaft position (CKP) sensor and the vehicle speed sensor (VSS) with 8 Volts DC. The BLK/LT BLU wire feeds Ground (from the PCM) to several sensors (including the camshaft position sensor).
