How to Repair P0132 Trouble Code?
1 Answers
p0132 trouble code repair method: First inspect the wiring harness of the pre-catalytic converter oxygen sensor, replace the pre-catalytic converter sensor and engine control module, then clear the fault according to the trouble code. The P0132 trouble code applies to all automobile manufacturers and represents high voltage in the oxygen sensor circuit. The function of the oxygen sensor is to measure the oxygen content in the engine exhaust to adjust the fuel injection volume, thereby enabling the engine to achieve an optimal air-fuel ratio. Its core component is a porous ZrO2 ceramic tube, which is a solid-state electrolyte with porous platinum electrodes sintered on both sides. At a certain temperature, due to the difference in oxygen concentration on both sides, oxygen molecules on the high-concentration side are adsorbed on the platinum electrode and combine with electrons to form oxygen ions O2, making this electrode positively charged. O2 ions migrate through oxygen ion vacancies in the electrolyte to the low-oxygen-concentration side, making that electrode negatively charged, thus generating a potential difference.
