Jan 7, 2023 · The P2135 code indicates that the voltage reading between the accelerator pedal position sensor and the throttle body position sensor doesn’t match. This isn’t an issue on older models because the throttle body was connected directly to the accelerator with the help of a cable and a mechanical link.

To solve the P2135 fault code, replace the throttle position sensor and reprogram the engine control module. Steps to fix are listed inside.

AM2315C consists of an all-new-design ASIC dedicated chip, an improved MEMS capacitive humidity sensor, and a standard on-chip temperature sensor. The performance and reliability have been greatly improved, surpassing the level of the previous generations.

Symptoms of a P2135 code can range from stalling when you come to a stop, total lack of power, no acceleration, sudden loss of power at cruise speeds or stuck throttle at current rpm. Additionally, the check engine light will illuminate and the code will be set.

Sep 9, 2024 · Code P2135 stands for "Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation". It indicates the engine control module (ECM) has detected the voltage signals from the throttle position (TP) sensor and accelerator pedal position (APP) sensor do not match each other as expected.

Feb 22, 2024 · DTC P2135 indicates that the voltage present at a vehicle’s APP (accelerator pedal sensor), and that found at the TPS (throttle position sensor), are not in agreement. As such, a vehicle’s PCM determines that the engine’s throttle position is …

Causes and Fixes Chevy/GMC P2135 Code: Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation. Symptoms of a Bad Throttle Position Sensor and How Se...

Aug 29, 2016 · Known as drive-by-wire, these systems use a sensor at the accelerator pedal to determine its position. Then, a signal is sent to a sensor on the throttle body to adjust the position of the throttle plate. This action is performed in real-time, and response is virtually instantaneous.

Jun 30, 2021 · DTC P2135 stands for “Throttle/Pedal Position Sensor/ Switch A/B Voltage Correlation.” This code triggers when the PCM detects a problem with your vehicle’s throttle or pedal position sensors/switches.

Jan 1, 2025 · The OBD2 code P2135 indicates a voltage correlation error between Throttle Position Sensor/Switch “A” and “B”. This essential component tells your car’s computer how much gas you’re giving it.
