Details of the Chrysler p0038 OBD Code
Chrysler fault code P0038 relates to a malfunction in the HO2S heater control circuit bank 1 sensor 2.
Code P0038 for Chrysler vehicles indicates a fault with the Heated Oxygen Sensor (HO2S) Heater Control Circuit High (Bank 1 Sensor 2).
This code is triggered by the Engine Control Module (ECM) when it detects a high voltage condition in the heater circuit of the downstream oxygen sensor located after the catalytic converter in bank 1 of the engine.
The ECM monitors the voltage signal from the downstream oxygen sensor to ensure it is operating within a specific range.
A high voltage reading in the heater circuit suggests an issue with the sensor’s internal heater or the wiring associated with it.
This can lead to inaccurate sensor readings and affect the vehicle’s fuel mixture control and emissions performance.
