What does the p1131 code on the ho2s mean?
If all tests have passed so far, and you continue to get a P1131 code, monitor the HO2S. If it continually indicates that the engine is running lean (voltage continually below .5 volts), locate any and all possibilities that could cause a lean running engine. These include but not limited to:
What are the possible causes of Ford p1131 code?
P1131 FORD Possible Causes. Faulty Upstream Oxygen Sensor Bank 1. Fuel pressure high or low. MAF sensor dirty/defective. Vacuum leak on engine. Leaking fuel injector or fuel pressure regulator. Faulty Powertrain Control Module (PCM)
What does the p1131 Ford heated oxygen sensor do?
P1131 Ford Description The Heated Oxygen Sensor(HO2S) Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions.
What does the error code p1151 stand for?
Error Code P1151 is defined as Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 2. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies exclusively to Ford vehicles.
P1131 FORD Possible Causes. Faulty Upstream Oxygen Sensor Bank 1. Fuel pressure high or low. MAF sensor dirty/defective. Vacuum leak on engine. Leaking fuel injector or fuel pressure regulator. Faulty Powertrain Control Module (PCM)

What’s the difference between p1151 and p1131?
P1151 – Upstream Heated O2 Sensor or Fuel System Not Switching Indicating Lean Bank 2 – Same as P1131 but for bank 2. P0171 and P0174 – System Too Lean Bank 1 and Bank 2 – Same diagnostic indications and steps as P1131 and P1151, but their requirements to set are different.
What does p1131 mean on a powertrain control module?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The code means that the Powertrain Control Module (PCM) has detected a lean system, which means that there is either not enough fuel or and excessive amount of air in the system. Start by checking for vacuum leaks.
