What does the trouble code p0123 mean?
What does the trouble code p0123 mean?
Meaning, the PCM (powertrain control module, also referred as ECM or engine control module) has determined the TPS Circuit A output voltage range has gone higher than the sensor’s voltage specification. It’s a generic trouble code, which means it applies to all vehicles made since 1996 to present.
How does the p0123 throttle position sensor work?
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.
What causes the p0113 check engine light code?
As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.
What does the p0132 sensor circuit high voltage mean?
02 Sensor Circuit High Voltage (Bank 1 Sensor 1) What the P0132 code means When the P0132 trouble code has been stored by the power control module, it is an indication of a problem with the 02 oxygen sensor. Specifically, that the oxygen sensor has stayed at a high voltage for too long without switching back.
What do you need to know about p0123?
Cost of diagnosing the P0123 code. P0123 is a diagnostic trouble code (DTC) for “Throttle Pedal Position Sensor/Switch (TPS) A Circuit High Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Why is my p0123 throttle position sensor not working?
Here are some of the reasons why the P0123 trouble code generates. • Throttle position sensor not positioned correctly. • Throttle position sensor short circuit. • Defective throttle position sensor. • A defective pedal position sensor. • Contaminated throttle body. • Poor or damaged wiring.
What does p0193 mean on a fuel rail sensor?
P0193 is a diagnostic trouble code (DTC) for “Fuel Rail Pressure Sensor Circuit High Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What causes the p0193 check engine light to come on?
The power control module (PCM) has detected that the fuel pressure is not within a range that has been predetermined by the vehicle manufacturer. When this happens the P0193 trouble code will be stored by the power control module and the Check Engine Light will come on. What causes the P0193 code? What are the symptoms of the P0193 code?
