What is the solution for the P0137 trouble code?
1 Answers
Solution for the P0137 trouble code: First, check the heater resistor wire of the oxygen sensor. If it is faulty, the heater resistor wire of the sensor needs to be replaced. If the resistor wire is normal, check the wiring from the sensor to the computer. If the wiring is fine, it indicates a sensor fault, and the entire sensor needs to be replaced. Introduction to the P0137 trouble code: 1. The P0137 trouble code refers to low voltage in the oxygen sensor circuit, specifically the second oxygen sensor in the first row. When the voltage of the heated oxygen sensor signal remains below 156 millivolts for a set period, the P0137 trouble code will appear. 2. The causes of this trouble code include contamination of the oxygen sensor, crossed signal and ground circuits of the oxygen sensor, short circuit in the oxygen sensor signal circuit, failure of the oxygen sensor itself, or a fault in the electronic control module.
