What does error code p0038 mean on ho2s?
Error Code P0038 is defined as HO2S (Heated Oxygen Sensor) Heater Control Circuit High Bank 1, Sensor 2. It’s a generic definition which usually means there’s a problem with the heater element circuit of the HO2S. Different manufacturers may have different definitions…
What does OBD II fault code p0038 mean?
What Does Code P0038 Mean? OBD II fault code P0038 is defined as “Oxygen Sensor Heater Control Circuit High (Bank 1 Sensor 2), and is set when the PCM (Powertrain Control Module) detects a signal voltage from oxygen sensor #2 that does not fall within the predefined range for that sensor.
How to set p0038 on oxygen sensor heater?
Input voltages in all oxygen sensor heater control circuits should be equal to battery voltage; deviations of 10% will also set code P0038 and trigger the CHECK ENGINE light. Note that the electrical resistance may differ on some applications- consult the manual on the exact values for the application being worked on.
Where is Bank 1 sensor 2 on the ho2s?
Bank 1 sensor 2 is located at the back of bank 1. The PCM uses the data from the HO2S mainly to monitor the catalytic converter’s efficiency, which is an extremely important component of the heater element. The PCM sets the operating temperature of the engine by controlling the heater to warm it up.
