SOURCE: need wiring diagram for the ecm on a 94 chevy s10

Throttle Position Sensor (TPS) is connected to the throttle shaft on the throttle body. It is a potentiometer with one end connected to 5 volts from the VCM and the other to ground. A third wire is connected to the VCM to measure the voltage from the TPS. As the throttle valve angle is changed (accelerator pedal moved), the output of the TPS also changes. At a closed throttle position, the output of the TPS is low (approximately 0.5 volts). As the throttle valve opens, the output increases so that, at wide-open throttle, the output voltage should be approximately 4.5 volts. By monitoring the output voltage from the TPS, the VCM can determine fuel delivery based on throttle valve angle (driver demand).

In addition, I send you some wiring diagrams that coud helpful (click image for zoom)...

Where is the manifold absolute pressure located on a pontiac grand am 2.4 liter

Right next to the throttle body and down to the right if you are facing the engine from the front. Chances are you have a broken vacuum line. Not often the sensor fails.

Mass air flow sensor location

3.1 liter - It will be in the air snorkel in between the air filter housing and the throttle body.

3.8 liter - it will be mounted in the throttle body right before the throttle.

Both will have a flat 3 wire connector.

How hard is it to replace thermostat on 3.4 liter pontiac grand am gt

it is a little bit tricky, but certainly do-able. you need to remove the throttle body to gain access to the thermostat housing, so make sure you buy a new throttle body gasket. to take this job on, you will need a few flex sockets and some extensions. make sure you are well equipped before starting this job. good luck!
