Sebring Convertible V6-2.5L SOHC 24 Valve (1996)
Throttle Position Sensor: Description and Operation
Related Trouble Codes & Set Conditions
No 5 Volts to TP Sensor
NAME OF CODE:
No 5 Volts to TP Sensor
WHEN MONITORED:
Vehicle speed above 20 mph, MAP sensor vacuum above 3 in., and engine speed above 1500 rpm.
SET CONDITION:
TP sensor signal goes below 0.5 volts.
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 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 61.
-
The sensor ground is provided by PCM cavity 43.
POSSIBLE CAUSES:
-
Open 5 volt supply
-
TP sensor failure
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 35 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 35. 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
Throttle Position Sensor Voltage Low
NAME OF CODE:
Throttle Position Sensor Voltage Low
WHEN MONITORED:
With the ignition ON.
SET CONDITION:
The Throttle Position (TP) sensor voltage at Powertrain Control Module (PCM) cavity 35 goes below 0.2 volt for 0.704 seconds, or MPH is
above 20, RPM is above 1500, and vacuum is below 2" with TP sensor voltage less than 0.5 volt for 0.704 seconds.
