Is there a fuse for oxygen sensor?
There are no fuses for the O2 sensors. They are controlled by the PCM.
What does O2 sensor heater circuit malfunction mean?
DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates that there’s a problem with the heater circuit of engine bank 1’s downstream O2 sensor. Your car’s PCM tests the oxygen sensors’ heater circuits for integrity.
Where is the fuse box on a 1998 Pontiac Bonneville?
Biggest one is under the hood. Remove the black cover that is along the backside of the engine…its right in front of the cowling. That’s where your maxi-fuses are. Second location is under the steering column.
What is the ECU fuse?
The electronic control module (ECM) — also called the powertrain control module (PCM) or electronic control unit (ECU) — is a computer which controls the electronics in an automobile. Many component defects can cause your ECM 1 fuse to blow.
Can I drive with a bad O2 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.
Where is the TCM fuse located?
The transmission control module can often be found below the cover at the back of the transmission case. It should be just below the engine control module’s position. Sometimes it’s found under the center console in the interior or even under the hood near the battery or inner fender panel.
What happens if ECU fuse is blown?
The voltage or amps surge, causing the ECM 1’s fuse to blow. When the starter fails you will hear a clicking noise or the engine will be hard to start.
What is the OBDII code on a Pontiac Bonneville?
P0135 is a very common OBDII code that occurs in the Pontiac Bonneville. It is caused by a failure in one of the oxygen sensors heated elements, specifically bank 1 sensor 1. It technically stands for:
Can a heater with an oxygen sensor fail?
Oxygen sensor heaters do fail. But there are other possible causes for a heater DTC. Before screwing in a new sensor, this simple test will determine whether everything else is in order.
When does the O2 sensor on a car fail?
As vehicles grow older, there comes a point when the oxygen or air/fuel ratio sensor’s heater circuit will probably fail. When that happens, the easiest fix is to install a new sensor.
How many wires does an oxygen sensor have?
However, oxygen sensors can have five or more wires. These sensors will still have two dedicated heater wires. Once you match the plug and wiring configuration to the vehicle’s O 2 sensor connector, you’re ready to start testing.
