P0161 Code: Causes, Symptoms, and P0161 Repair Cost
Understanding the P0161 Code and Typical Repair Costs Quick Summary The P0161 code is a common diagnostic trouble code indicating a problem with the oxygen sensor heater circuit on Bank 1, Sensor 1. In simple terms, the engine computer has detected that the heater element inside the upstream oxygen sensor is not working properly. This heater is critical because it brings the sensor up to operating temperature quickly, allowing the engine computer to accurately control the air-fuel mixture. The most common causes of a P0161 code include a failed oxygen … 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
