P0137 trouble code: What it means and how to fix it
Learn what a P0137 trouble code means and how to fix it A P0137 trouble code is defined as: Oxygen Sensor Circuit Low Voltage (Bank 1 Sensor 1). This sensor is located on the engine bank that houses #1 cylinder and is located AFTER the catalytic converter. The oxygen sensor measures oxygen levels in exhaust gases post-combustion to optimize engine performance and minimize air pollution. If oxygen levels are too low, indicating a rich fuel mixture, the PCM reduces fuel delivery. Conversely, if oxygen levels are too high, indicating a … Read More
P2135 Code — What it means, how to fix
Learn what a P2135 code means and how to diagnose and fix the problem A P2135 code is defined as Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation. A throttle position sensor tells the ECM exactly how far to open or close the throttle plate. This code is used almost exclusively in engines equipped with an electronic throttle body and an electronic accelerator pedal (gas pedal). In these “drive by wire” systems, the ECM receives input from the accelerator pedal and transmits the commands to the electronic throttle body. Both the accelerator … Read More
