How do I fix code P0030?
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 causes a P0030 code?
What causes the P0030 code? Generally, if the code is cleared and reset, and the engine warning light comes back on along with the OBD-II code, this means that the HO2S sensor for the engine bank 1 and sensor 1 is not sending the proper signals to the ECM. The ECM may be defective or has defective wiring.
Where is the oxygen sensor bank 1 located?
The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2. On V6 and V8 engines, Sensor 1 will always be on the SAME side as the Number ONE cylinder in the engine’s firing order.
What is heater control 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.
What is a heater circuit malfunction?
This code indicates that the Engine Control Module (ECM) has tested the oxygen sensor heater circuit and has found a problem with sensor 1 in bank 1. If the ECM detects an open circuit, a short-circuit, or excessive current draw in the heater circuit, it will set the P0135 code.
Which side of the engine is bank 1?
Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine.
What is a bank 1 sensor?
A typical in-line 4-cylinder engine has only one bank (Bank 1). Therefore, in an in-line 4-cylinder engine, the term “Bank 1, Sensor 1” simply refers to the front oxygen sensor. A V6 or V8 engine has two banks (or two parts of that “V”). Usually, the bank that contains the cylinder number 1 is called “Bank 1.”
What is P0030 diagnostic code?
Diagnostic Trouble Code (DTC) P0030 stands for “HO2S Heater Control Circuit (Bank 1, Sensor 1).” It may be triggered when your vehicle’s control module detects a fault in the heater circuit in oxygen sensor Bank 1, Sensor 1. Your engine must have the correct air-fuel ratio for it to run efficiently.
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 does the DTC code p0030 stand for?
Code P0030 may be set by your PCM if there’s a fault in the heater circuit in oxygen sensor Bank 1, Sensor 1. What Does the P0030 Code Mean? Diagnostic Trouble Code (DTC) P0030 stands for “HO2S Heater Control Circuit (Bank 1, Sensor 1).”
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
