The MAP Sensor is on the back side of the engine, toward the top-middle. There should be a bracket w/ a hose coming out of the center. The MAP Sensor should be just to the left of the hose (Passenger Side).
Assuming that it is a 3.1 V6, as most of them are, there is no cam sensor. Only a crankshaft sensor. It is located behind the harmonic balancer. To replace it the balancer has to be removed.
On a 1993 Chevy Lumina with a 3.1L engine, the crankshaft position sensor is located near the crankshaft pulley at the front of the engine. It is mounted on the engine block, typically on the passenger side. To access it, you may need to remove the engine cover or other components that obstruct the view.
There is no cam sensor on a 93 3.1. Just a crankshaft sensor....which is located behind the harmonic balancer. WRONG! it does in Fact have a cam position sensor! its underneath the intake plenum!
There is no cable....It's all done with a sensor and electronics.
Lumina in USA does not have a carburetor
I have a 1993 Chevy lumina van that has heat but doesn't have a fan how do I fix the fan?
A
on most cars it in the front at the bottom of the by the crank pully
The crank sensor is located on the rear of the engine,on the right hand side about 5 inches from the oil pan.
I had to go to a dealership in order to find the location of the cam position sensor on a 1993 / 3.1 chevy lumina. I could order the part but was unable to find the location. after returning from the dealership. I am here to discredit those who say it doesn't have one. it in FACT does have one!. It is located under neath the intake plenum..
It is located either on the manifold or somewhere on the exaust
That year did not have a crank sensor on it.
