How does the p0030 ho2s heater control circuit?

How does the p0030 ho2s heater control circuit?

The computer activates the heater under certain circumstances by completing the ground to the oxygen sensor heater. On other vehicles the O2 sensor heater may be supplied a computer controlled 12 volts feed and continuous ground. If the ECM detects a fault on the Bank 1, sensor 1 heater circuit a P0030 may set.

What is the engine code for a ho2s heater?

Replace and re-check. Engine codes P0135 (HO2S Performance Bank 1 Sensor 1) and P0030 (HO2S Heater circuit Bank 1 Sensor 1). I replaced the upstream oxygen sensor (bank 1 sensor 1) with an NGK 21546 however the MIL is still on.

What does p0030 stand for on an oxygen sensor?

Code P0030 stands for Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). This indicates the PCM has detected a problem with the bank 1 oxygen sensor. Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. If you’ve got a four-cylinder, there will only be one bank.

What are the symptoms of a p0030 heater fault?

If the ECM detects a fault on the Bank 1, sensor 1 heater circuit a P0030 may set. Symptoms of a P0030 DTC may include: Possibly decreased fuel mileage depending on fault Potential causes of a P0030 trouble code may include: Failed or damaged heater circuit element inside the HO2S
