Throttle Position (TP) Sensor
WARNING: This page is about a different car, the 1998 Honda Odyssey, 1998 Honda Accord, and 1998 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.
TP sensor should input a .5-volt signal to PCM at closed throttle. At full throttle, signal should be approximately 4.5 volts. Voltage should change smoothly as throttle valve is opened and closed. If voltage is not as specified, check throttle position sensor wiring circuit. See WIRING DIAGRAMS .
NOTE:
If a problem in TP sensor is present, sensor may set DTC P1790/3 in PCM. See RETRIEVING FAULT CODES
under SELF-DIAGNOSTIC SYSTEM.
