If the engine is a 2.4L four cylinder engine, the crankshaft position sensor is located on the engine, passenger side, where the crankshaft comes out of the engine, on the lower side. You can see the sensor from the top side, with a 2 point wire connector on it. Just disconnect the wire, and use a deep socket to remove the sensor from the engine. It should come out without spilling any oil, and if you have a new sensor available, be sure to match the O-ring on the old sensor, then lubricate the O-ring with oil, and push the new sensor in, bolt it down, reconnect the wire, and the job is done.

What does a crankshaft sensor do? what does a camshaft sensor do?

get a HAYNES repair manual, tells you what all sensors do ! the crankshaft sensor sends info to the SBEC, reguarding engine crankshaft position. the camshaft sensor reads camshaft position, sends a coded signal to the SBEC, which uses this info to determine whether the fuel injectors and ignition coils are correctly synchronized !

Hi rafymoctezum,

The crankshaft sensor for your car is located near the starter. The best way to see it is to remove the driver's side microfilter housing and connected air tube. If you are looking at the starter, the crankshaft sensor is located to the right and is held in place with a 5mm allen bolt.

1997 Chrysler LHS 3.5 cars turning over, no spark, plenty of fuel...looking for the crankshaft position sensor...can you tell me the location?

Good Evening, I know you might be having a harder time finding that sensor. It is not in the place a usual car would be, instead it is on the passenger side in the front part of the transmission. If you look in your engine compartment and take off the breather (air intake) tube now look down right passed the motor right past the bell bolts bout 3 inches or so it is right there held in by a 10mm if i remember it right. Hope this helps, and if you have any more questions please feel free to ask.

Where does the crankshaft position sesor go on a lincoln aviator 03?

The crankshaft sensor sit between the a/c compr and the crankshaft pulley, sensor bolts to the side of timing chain cover, only 1 bolt holds it in place, only one, disconnect sensor harness, remove 10 or 8 mm bolt, sensor will slide right out. Hope this was very helpful.

I have a 1991 chevy truck, I am getting no spark. I have changed the ECM, distributor and coil. still no results. I have no idea of what to do.

check to see if your truck has a crankshaft position sensor, its usually located behind the harmonic balancer or right near there, if the sensor went bad or if the wiring got messed up there will be no signal to the ecm telling the ecm when to send spark to the coil. the crankshaft position sensor is responsible for telling the computer when to fire the spark plugs based on rpm and timing. check the wires on the crankshaft position sensor, if they look fine, replace the sensor, hope this helps!

Where is the crankshaft sensor located in a 2001 jeep cherokee sport?

Your sensor is located next to the crankshaft pulley. it is halfway into the block and, the housing will have wire clips protruding outwards. it should be around the top left or right side of the pulley.
