October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Throttle Position Sensor (TPS)

TPS, mounted on the injection pump, is a variable resistor monitoring throttle opening angle for the ECM. The sensor is connected to a 5-volt reference signal and has a high resistance value when throttle is closed. At wide open throttle, the TPS resistance value is low, and output to the ECM will be near 5 volts.
