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 are the possible causes of p0123 Mercedes-Benz?
P0123 MERCEDES-BENZ Possible Causes 1 Faulty Accelerator Pedal Position Sensor 2 Accelerator Pedal Position Sensor harness is open or shorted 3 Accelerator Pedal Position Sensor circuit poor electrical connection 4 Faulty Throttle Position Sensor (TPS) 5 Faulty Engine Control Module (ECM) More …
What does the p0123 code on the ECM mean?
The P0123 code indicates a problem with the throttle/pedal 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 are the symptoms of the p0123 OBD-II trouble code?
The TPS sensor circuit A range output to the ECM went above the specified voltage of 4.54 volts for more than 2 seconds, indicating a short in the sensor or wiring. What are the symptoms of the P0123 code?
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 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.
What’s the problem with the TPS code p0120?
The P0120 code may be accompanied by other TPS codes, so following the manufacturer pinpoint tests for each code received may be needed to fix the complaint. Most failures for code P0120 involve a defective TPS sensor not tracking the throttle angle correctly.
What are the symptoms of the p0120 OBD-II trouble code?
The ECM detected that the output from TPS sensor circuit A went outside of the specified voltage range in relation to TPS sensor circuit B. The TPS sensor circuit A output falls below .2 volts or goes above 4.5 volts. What are the symptoms of the P0120 code?
What causes a throttle actuator to set code p0638?
Common causes of code P0638 could include the following-. Damaged, burnt, shorted, corroded, or disconnected wiring and/or connectors. Note that wiring issues in almost any part of the CAN bus system that is involved in throttle control can cause this code to set. Defective throttle actuator.
Why does my car keep throwing the p0121 code?
Haven’t had many issues with this car, it threw the p0121 first, then a couple days later, today, threw p2135. The way I’m thinking, having both these codes show up is pointing to my pedal position sensor being faulty. Im thinking the p2135 boils down to the pedal position and throttle position sen…
What is the OBD II fault code p0638?
OBD II fault code P0638 is a generic code that is defined as “Throttle actuator control, Bank 1 -range/performance problem”, and is set when the PCM (Powertrain Control Module) detects a problem with the operation of the throttle control actuator on drive-by-wire systems.
