The camshaft position sensor on a 1991 Acura Legend is located at the back of the camshaft, near the rear bearing cap. It monitors the rotation of the camshaft and relays this information to the vehicle's computer.
On the 3.1L & 3.8L engines, the CMP sensor is located on the timing cover, behind the water pump, near the camshaft sprocket.
On vehicles equipped with a camshaft position sensor, it is used to help the PCM determine the correct firing order.
under the water pump.
engine light will go on and give you code
Cam sensor is inside the distributor under pick-up coil. Some say whole distributor has to come out to replace, some have snuck it out by removing pick-up coil.
On the V6 its in the block between the two heads and right behind the timing chain
The 1991 Saturn throttle position sensor can be found on the firewall in the engine compartment. The throttle position sensor will be on the drivers side of the firewall.
inside the distributor
The 1991 Ford Explorer 4.0 engine does not use a cam sensor, but rather a crank sensor at the lower front of the engine to set crank or time position, two bolts and one connector.....
Driver side of the bell housing.
It is located on the firewall side of the engine. Towards the passenger side. Just above the oil pan. (The original respondent) just replaced one on a 1991 3.1 liter. I was lucky that I had access to a lift. It was sort of a pain but I got it replaced in about 45 minutes. The bolt is 8mm. Use a 1/4 drive with a long extension.
paste this into your browser...i could not get the link box to take.. but this should ansewr the question on the o2 sensor
its behind the coil packs on the back of block
It is located on the bell housing on the driver's side of the vehicle.
No crank sensor, only a cam position sensor.
The idle sensor on a 1991 S10 4.3 can be located at the engine bay.
In the distributor.
I replaced one on an 89 LeSabre 3800 V6. The camshaft sensor on this engine was located on the passenger side of the engine. You will need to remove the serpentine belt, and you can get to it by removing the inner fender or splash guard and get to it that way. I went down from the top. There are two sensors, one is a CRANKSHAFT sensor and other is a cam sensor. Make sure you know which is which. The crankshaft sensor is at the bottom of the engine, the camshaft is right by the water inlet. It is held in by 1 or 2 bolts. If your car is throwing the code for the camshaft sensor, just a heads up. I replaced the sensor and the sensor detects magnets installed on the camshaft. The engine kept throwing the code and came to find out one of the magnets had come off the end of the cam. I am telling you this just in case you go through the replacement and still end up with the code. I was still able to drive the vehicle with the check engine light on with the missing magnets. the camshaft sensor is not too hard to replace, it's tight but it can be done. unbolt the old and bolt in the new. Make sure you disconnect battery before tackling this project.
No crank sensor, only the sensor in the distributor.
There is a crankshaft position sensor that measures how fast it rotates
It is located inside of the distributor.
You adjust the timing by moving the crank angle sensor. The crank angle sensor is driven by the camshaft closest to the intake manifold (passenger side of the engine) and is located behind the cylinder head and valve cover. Losen the bolt that secures the crank angle sensor, in order to move the crank angle sensor.
if you are facing the engine it will be on the left upperside of the crank pully, on a target wheel. is it hard to remove and replace
The Camshaft and crankshaft sensors sit behind the main pully, you really need a mechanic to change this because if you don't torque it right they will shift and you will have to replace them again. The parts are only about $40 a piece but the labor will run you about 2-$300.
