What causes P1153 code?
A P1153 code is a generic diagnostic trouble code that occurs when the PCM/ECM detects a signal voltage input indicating an issue with the HO2S sensor which is installed in the exhaust manifold. It controls the unburned oxygen in the exhaust once it comes out from the engine.
What side is bank 2 on a Chevy?
Bank 2 Locations
| Vehicle | Bank 2 Sensor 1 Location |
|---|---|
| Chevrolet Colorado | Passenger side with cylinder 2 in the firing order, in front of the catalytic converter |
| Ford Bronco | On the exhaust end, before the catalytic converter |
| Ford Ranger | Driver side, before the catalytic converter |
| GMC Sierra | Passenger side, before catalytic converter |
What is P1133 and P1153?
A DTC P1133 or a DTC P1153 sets when the PCM determines that the HO2S did not switch enough times. A lean-to-rich switch is determined when the HO2S voltage changes from less than 300 mV to more than 600 mV.
How do I fix code P1133?
How to repair the P1133 error code?
- Repair the leaks in vacuum systems.
- Replace the broken or shorted HO2S bank 1 sensor harness.
- Repair or replace the poor electrical connection in HO2S bank 1 sensor 1.
How do I fix code P0151?
What repairs can fix the P0151 code?
- Replacing the O2 sensor for bank 2 sensor 1 if all tests indicate a failed sensor.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 2 sensor 1.
- Repairing exhaust leaks before the sensor that introduce excessive oxygen into the exhaust.
What can cause a P0151?
There are multiple factors that could cause the activation of the engine code P0151….What are the Possible Causes of Code P0151?
- A faulty front O2 sensor (bank 2)
- An issue with the O2 sensor’s circuit.
- A lean running condition.
- An exhaust leak.
What causes O2 sensor low voltage?
A low voltage signal from the oxygen sensor indicates low oxygen content in the exhaust—a sign that the engine runs rich. The PCM responds by reducing the fuel going to the engine.
