The crankshaft position sensor on a 1987 Chevrolet Celebrity is on the side of the engine nearest the firewall. I need to know which engine to give a more specific answer.
No it does not have a crankshaft sensor, the engine control module uses the distributor for crankshaft position.
The crankshaft position sensor is located at the driver's side bell housing. There are two sensors exactly alike being held with an Allen bolt. The one sensor closest to the front of the car is the speed sensor and the one closest to the rear of the car is the crankshaft position sensor. Hope that helps...
The crankshaft position sensor is located on the lower engine block beneath the exhaust manifold on the firewall side of the engine.
On a 1987 to 1990 Celebrity with 2.8/3.1L engine the crankshaft position sensor is on the side of the block beneath the exhaust manifold on the firewall side of the engine.
were is the crankshaft sensor located on a 1987 Pontiac Grand AM with a 2.5L engine
The knock sensor on a Chevy Celebrity 2.8 L engine from 1987 thru 1990 is located on the back side of the engine(next to the firewall) below the exhaust manifold. There are actually two sensors there, one is the knock sensor, the other is the crankshaft position sensor. The knock sensor is threaded into the block with a pipe thread, the crankshaft position sensor is held in with a 10 mm screw and is near the center of the block. They are both accessible with the engine in the car, but they are a bit of a pain to get to.l
The throttle position sensor is on the throttle body.
It on the back of the coil packs going into the side of the block.
To check the crankshaft position sensor on a 1987 - 1990 Chevy Celebrity: 1. Set the parking brake. Raise the car as necessary and put on stands so that you can get to the underside of the engine at the ignition module. 2. Locate the wire from the crankshaft position sensor to the ignition module. It should have a yellow and a purple wire. 3, Measure the resistance between the two wires. It should be between 900 and 1200 ohms. If it does not read that amount it is probably faulty OR you have a problem in the wiring. There can be a problem with this though. If the sensor is good cold it can still be faulty when it gets hot. The ignition module itself can also have the same problem. If you put on a known good sensor and the problem goes away, then the sensor was probably your engines problem. WE have a car that would run fine until it got hot. It would then quit running and not start again till it got cold. We replaced both the crankshaft position sensor and the ignition module and the problem WE were having went away.
This could be caused by either a failing crankshaft position sensor and /or ignition module. It works alright when it is cold, but when it gets hot it quits. If that is the case either will ultimately fail altogether. I actually had that happen on a 1987 Celebrity that I own. First the crankshaft position sensor failed, I had no sooner replaced it when the ignition module died. Both failed in the same day.
I had a similar experience with my 1987 Chevy Celebrity. In my car's case I replaced the ignition module and the crankshaft position sensor. Between the two the problem seems to be fixed.
