What vehicles are most commonly affected by P2136?

Commonly affected vehicles include the 2010-2015 Chevrolet Malibu, 2011-2016 Ford Fiesta, and various models from Honda and Toyota. Check for any recalls or technical service bulletins (TSBs) related to your vehicle.

How can I prevent P2136 from happening again?

Regular maintenance, including cleaning the throttle body and checking electrical connections, can help prevent P2136. Additionally, routine diagnostics using tools like the GeekOBD APP can identify issues early.

What is P2136?

The Diagnostic Trouble Code (DTC) P2136 indicates a throttle position sensor (TPS) issue, specifically a range or performance problem. This occurs when the Engine Control Module (ECM) detects an inconsistency between the readings from the throttle position sensors. Many modern vehicles, including popular models like the 2010-2015 Chevrolet Malibu, rely on these sensors to determine how much air enters the engine, which is critical for optimizing fuel efficiency and engine performance. When the ECM detects that the TPS readings are not within the expected range, it triggers the P2136 code. This can lead to a range of issues, including reduced engine performance, unexpected acceleration, or stalling, making it crucial for car owners to address this promptly. Ignoring this code may result in more severe engine performance issues and can impact the vehicle's fuel economy. Drivers may notice that their vehicle struggles to accelerate smoothly or experiences erratic power delivery. If you find your vehicle exhibiting these symptoms, it's essential to diagnose and resolve the underlying issue to maintain optimal performance and safety.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P2136 is present:

  • The check engine light is illuminated, often remaining lit until the issue is resolved.
  • Engine hesitates during acceleration, causing a noticeable lag when pressing the gas pedal.
  • Fuel economy decreases significantly, often by 10-15%, impacting your budget.
  • The vehicle may enter 'limp mode,' restricting engine power and speed to protect the engine.
  • Unusual engine stalling can occur, especially when idling or during low-speed driving.

Possible Causes

Most common causes of P2136 (ordered by frequency):

  1. The most common cause is a faulty throttle position sensor, occurring in about 70% of cases. This can happen due to wear over time or exposure to heat and moisture.
  2. Another potential cause can be damaged wiring or connectors related to the TPS, which can disrupt communication with the ECM.
  3. A third cause could be a dirty throttle body, which can affect sensor readings and throttle response. Regular cleaning can help prevent this.
  4. Less common but serious causes include a malfunctioning ECM, which may misinterpret sensor data, leading to erratic engine behavior.
  5. A rare but possible cause is an issue with the accelerator pedal position sensor, particularly in vehicles with drive-by-wire systems.
