When to replace O2 sensor in Ford Ranger?
When to replace O2 sensor in Ford Ranger?
There is a Ford Technical Service Bulletin (TSB) 14-0084 which applies to some 2010-2012 F-150, Navigator, Ranger, E-Series and other vehicles which refers to replacement of the O2 sensor if DTCs P2270 or P2272 are observed.
Why is Bank 1 O2 sensor signal stuck lean?
This means that the O2 sensor in bank 1 sensor 2 indicates either too much oxygen in the exhaust stream, an open circuit, or a defective sensor which causes a lean signal to the ECM.
What does the p2272 O2 sensor signal stuck lean lean?
The converter’s job is to reduce emissions out the tailpipe. When the signal from the O2 sensor is detected by the PCM as being stuck lean or biased lean, this DTC is set. The P2272 DTC refers to downstream sensor (after the catalytic converter), sensor #2 on bank #2. Bank #2 is the side of the engine that does not contain cylinder #1.
What can cause an O2 sensor to set a different code?
There are also some other possibilities such as an internally leaking EGR system. This will typically set a separate code. A leak in the exhaust system before the (O2) sensor will also cause incorrect readings. The only other possibilities are wiring issues, and computer concerns.

What is the diagnostic code for O2 sensor signal stuck lean?
P2195 is a diagnostic trouble code (DTC) for “O2 Sensor Signal Stuck Lean Bank 1 Sensor 1”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Where do I find the lean fault code on my car?
So your car’s CEL (always check Engine Light) is on and also you had the codes scanned at a local parts shop. (Or maybe used your own OBD scanner to extract the car faults). Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings.
What causes bank 2, sensor 2 to get stuck?
Watch the bank 2, sensor 2 reading. The rear heated oxygen sensor (HO2S) normally sees a fluctuating voltage between 0 & 1 volt, for this DTC you’ll likely see the voltage “stuck” at 0V. Revving the engine should cause the sensor’s voltage to change (react).
