What is a heater control circuit sensor?
What is a heater control circuit sensor?
The heater is an integral part of sensor function that is used to heat the oxygen sensor to operating temperature until the vehicle warms up. Oxygen sensors must be at operating temperature to provide accurate readings to the ECM for air fuel ratio control. This code may be seen with P0051.
What are the p0032 heater control circuit codes?
The codes I am getting are: P0032 HO2S Heater Control Circuit High (Bank 1 Sensor 1) P0038 HO2S Heater Control Circuit High (Bank 1 Sensor 2) I I have an ’06 Jeep Wrangler w/4.0l, and at random intervals it throws the following 4 codes: P0032, P0038, P0052, and P0058.
When is the p0038 Dodge code detected?
When is the P0038 DODGE code detected? Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).
What causes a p0038 ho2s heater control circuit?
Potential causes of a P0038 code include: Open in the heater control circuit (12 volt PCM controlled systems) Short to B+ (battery voltage) in the heater control circuit (12 volt PCM controlled systems) Open ground circuit (12 volt PCM controlled systems) Short to ground on heater control circuit (On PCM ground controlled systems)
What are the symptoms of a p0038 DTC?
If the PCM detects an abnormally high voltage condition on the heater circuit, P0038 may set. This code is only referring to the heating circuitry half of the Oxygen sensor. Symptoms of a P0038 DTC may include: MIL (Malfunction indicator lamp) illumination There would likely be no other symptoms.

What causes a p0038 code on a heater?
Potential causes of a P0038 code include: Faulty Bank 1,2 HO2S (Heated Oxygen sensor) Open in the heater control circuit (12 volt PCM controlled systems) Short to B+ (battery voltage) in the heater control circuit (12 volt PCM controlled systems) Open ground circuit (12 volt PCM controlled systems)

What is fault code for oxygen heater Bank 2?
We recommend Torque Pro. 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.
