What are all the sensors on 91 Z/28's? I know I have to get a MAP sensor because there isnt one there. Probably an EGR valve and an EGR vacuum soleniod (not sure if the 85-88's are the same). I just want to make sure I have all right sensors for my car because some might be missing.

 

What are you trying to do?

 

Put my car back together. It has an older tpi in it.

 

ECT sensor, probably an IAT sensor

 

Here is a list I came up with. I think that covers most, if not all of them.
I put on everything that has an electrical connector to it.

Knock Sensor
Map Sensor
Throttle Position Sensor (TPS)
Oxygen Sensor
Coolant Temperature Sensor (CTS)
Intake Air Temperature Sensor (IAT)
Idle Air Control Valve (IAC)
Vehicle Speed Sensor (VSS)
Oil Pressure Sender
Coolant Gauge Sender
Egr Solenoid

 

Thanks for the list. It will be a big help when I start putting my engine and harness together.
