Sebring L4-122 2.0L DOHC VIN Y MFI (1995)
Throttle Position Sensor: Description and Operation
Throttle Position Sensor Voltage High
NAME OF CODE:
Throttle Position Sensor Voltage High
WHEN MONITORED:
With the ignition ON.
SET CONDITION:
Throttle Position (TP) sensor voltage at Powertrain Control Module (PCM) cavity 10 goes above 4.5 volts for 0.704 seconds.
THEORY OF OPERATION:
The throttle position sensor contains a potentiometer that is operated by the throttle blade shaft. As the throttle plate rotates, the TP sensor
provides a variable 0 to 5-volt signal to PCM cavity 10. The voltage is directly proportional to throttle angle. When the throttle plate is at rest, the
voltage is low. When the throttle is fully open, the voltage is high. With this signal, the PCM can determine precise throttle position under all
operating conditions. The TP sensor receives a 5-volt supply from PCM cavity 43. The sensor ground is provided by PCM cavity 51.
POSSIBLE CAUSES:
-
Sensor signal circuit open
-
Throttle position sensor failure
-
Sensor ground circuit open
