What is trouble code P0038?

What is trouble code P0038?

Diagnostic trouble code (DTC) P0038 stands for “HO2S Heater Control Circuit High (Bank 1 Sensor 2). The oxygen sensor in pre-OBD vehicles often only contains one wire. The PCM constantly looks for out-of-the-ordinary voltages or current draw in the heater circuits.

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.

How do you fix a heater control circuit?

To fix this, check for any blown fuses and disconnect the oxygen sensor connector. Using the voltmeter, with the engine off, check whether there’s a 12V fused battery feed to the heater element. If you see no voltage, then repair the short or open in the B+ feed circuit.

What is a HO2S heater control circuit bank 1 sensor 2?

The Bank 1, Sensor 2 refers to Bank 1’s second sensor on the back. The PCM will then use the information to monitor the catalytic converter’s efficiency. Heater element plays a very important component for its function. For the engine to run properly, the exhaust must have the specified air/fuel ratio of 14.7 to 1.

How do you fix trouble code P0157?

What repairs can fix the P0157 code?

1. Replacing the rear oxygen sensor.
2. Repairing of broken circuitry or shorted wires going to the oxygen sensor.
3. If the fuel pressure is abnormal, repairing the cause of the abnormality.
4. Repairing the engine coolant temperature sensor if it is faulty.

How do I fix code P0038?

As with error codes, troubleshooting for P0038 starts with a thorough visual check of all connectors and wirings associated with the troubled components. Check for any signs of damage, burnt, shorted or broken connectors and wirings. Fix and replace everything that is damaged.

How do you fix a P0058 code?

What repairs can fix the P0058 code?

1. The most common repair, as stated previously, is replacing the oxygen sensor itself.
2. Next, most common repair is fixing the wiring or connectors associated with the oxygen sensor in question.
3. The least common repair would be replacing a faulty powertrain control module.

How do you fix P0032?

The most common repairs to address the P0032 code are as follows: Have a certified technician verify the code with a scanner. Reset the fault codes and then perform a road test. If the P0032 code returns, then follow the test procedure.

What does Engine code P0031 mean?

The P0031 code is a result of the bank 1 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a seperate heater inside the sensor to get them to operating temperature quickly. If this code is set, the oxygen sensor heater is not working.

Is it OK to drive with a bad oxygen sensor?

Can You Drive With A Bad Oxygen Sensor? Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don’t leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.

What happens when the oxygen sensor goes bad?

If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine’s timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.
