How to check the accelerator pedal position sensor 1 circuit?
Check the APP sensor ground 1 circuit for an open or high resistance Measure the resistance of the APP sensor ground 1 circuit between the Accelerator pedal position sensor harness connector and the PCM harness connector. Is the resistance below 3.0 Ohms? Yes, go to step 7.
Which is the best magnetic pedal position sensor?
Infineon’s magnetic sensors are particularly suited for the demanding requirements of pedal position sensors and their main features are presented. The last section is dedicated to some particular aspects of magnetic pedal position sensors such as magnetic circuit design,
Where are app sensors 1 and 2 located?
The APP sensors 1 and 2 are integrated into one assembly located at the pedal assembly. Each sensor has a 5 volt reference circuit, a low reference circuit, and signal circuit. The Powertrain Control Module (PCM) reads the two signals individually and then compares the two signals as a redundant check of the pedal position.
What does the p0121 code on the throttle sensor mean?
The error code P0121 may indicate an issue related to your engine’s throttle position sensor. Like other throttle position sensor-related codes, this could lead to serious problems and can result in your vehicle not starting at all. Let’s take a look at code P0121 and its other potential consequences. What Does the P0121 Code Mean?
What is the OBD2 code for the gas pedal?
Code P2138 is an accelerator pedal position (APP) sensor or throttle position (TP) sensor code. In simpler terms, it’s an OBD2 code triggered when one of the two sensors in your gas pedal malfunctions.
Check the APP sensor ground 1 circuit for an open or high resistance Measure the resistance of the APP sensor ground 1 circuit between the Accelerator pedal position sensor harness connector and the PCM harness connector. Is the resistance below 3.0 Ohms? Yes, go to step 7.
When to call a mechanic for a bad gas pedal sensor?
If any of these symptoms occur or your car isn’t responding accurately when you press the gas pedal, you should pull over immediately and call a mechanic. Here is a more detailed list of the most common symptoms of a bad accelerator pedal position sensor.
The error code P0121 may indicate an issue related to your engine’s throttle position sensor. Like other throttle position sensor-related codes, this could lead to serious problems and can result in your vehicle not starting at all. Let’s take a look at code P0121 and its other potential consequences. What Does the P0121 Code Mean?
