Want this question answered?
The oxygen sensor on a 1989 Chevy Celebrity is located in the rear exhaust manifold on top about the center.
The oxygen sensor is in the middle of the exhaust manifold near the firewall.
Check the manifold, just before the headpipe.
You can replace the ignition control module and the crankshaft position sensor as required.
Code 44 is an Oxygen sensor code meaning exhaust is to lean. Replace Oxygen sensor. Then clear codes. This should solve the problem.
replace the coolant sensor, the one next to the thermostat housing.
Chevy did not use a crank sensor on that year.
That year did not have a cam sensor.
where do I find it
In the 1989 Grand Prix, the oxygen sensor is in the tail pipe. Look for a wire that is plugged into both the tail pipe and the undercarriage of the vehicle.
yes, it does have Oxygen sensors
In the exhaust manifold or downpipe
