When does a TPS sensor indicate a problem?
When does a TPS sensor indicate a problem?
If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc. Other TPS sensor and circuit related DTCs: P0120, P0121, P0122, P0123, P0124
What does TPS mean on a Dodge Dakota?
CASE 2: The throttle angle voltage DID NOT increase (and/or decrease) as you opened and closed the throttle plate. This tells you that the TPS is bad and causing the TPS trouble code lighting up the check engine light (CEL) on your 4.7L Dodge Durango (Dakota). Before you run out and buy it, I’m gonna’ suggest that you do two more tests.
What is the trouble code for the throttle position sensor?
When the engine control module (ECM) detects that the throttle position sensor ’s output voltage rating is exceeding the manufacturer specification, it generates the P0123 trouble code.
What happens to the TPS when the throttle is closed?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is higher than the normal upper limit, P0123 will set. other symptoms may also be present
Where is the TPS located on a 04 Durango?
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the throttle blade shaft. The 5.7L V-8 engine does not use a separate TPS on the throttle body.
When the engine control module (ECM) detects that the throttle position sensor ’s output voltage rating is exceeding the manufacturer specification, it generates the P0123 trouble code.
