The 1994 S10 uses a MAP sensor, not a MAF sensor. We need to know size engine you have in that S10.
It doesn't have a map sensor, it has a maf (mass air flow) sensor instead. The maf sensor would be located in the snorkel between the air filter box and the throttle body.
Top center of engine, 2.2 or the 4.3 engine.
The manifold absolute pressure (MAP) sensor is an important component to your 1994 General Motors Blazer/Jimmy's EFI system. This pressure sensor is located provisioned into the intake manifold assembly.
The sensor for the temp gauge in the 96 S10 4.3L would be the sensor located between #3 and #5 spark plugs, it has one wire plugged to it. The temp sensor for the ECM is located next to the thermostat housing, it has two wires plugged to it.
under the coil pack rr of engine block
The idle sensor on a 1991 S10 4.3 can be located at the engine bay.
on the top of the intake
There is no adjustment to my knowledge.
There is more than one O2 sensor on that vehicle, and they are all threaded into the exhaust system at various points.
If that S10 has a 4.3 engine, I find it best to remove the distributor to gain better access to the oil pressure sensor.
does not have one just a map sensor
