Deceptive Oxygen Sensor Codes An inefficient catalytic converter. Engine vacuum leaks that create a lean exhaust condition. Mass airflow sensor failure that creates a rich exhaust condition. Manifold air pressure sensor failure that creates a rich exhaust condition.
How do I fix code p1152?
Repairs for this error code are as easy as its diagnosis, which include:
- Repair or replacement of MAF sensors.
- Repairs of leaks or replacement of Intake Air System.
- Repair or replacement of fuel pump and/or fuel injectors.
- Repair of leaks or replacement of leaks in exhaust system.
What causes a Ford engine to have code p1131?
Code P1131 can be caused by a vacuum leak, fuel injector problem, ignition problem or by a faulty oxygen sensor. You can find the oxygen sensor that reports this condition in the exhaust pipe for engine bank No.1, before the catalytic converter. Inspect the engine’s vacuum lines first.
How much does it cost to repair a p1131 Ford?
Please try again later. The cost of diagnosing the P1131 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
What should ho2s voltage be on Ford p1131?
Rich of stoichiometric, the HO2S will generate a voltage between 0.45 and 1.0 volt. • The HO2S Monitor evaluates both the upstream (Fuel Control) and downstream (Catalyst Monitor) HO2S for proper function. • Once the HO2S Monitor is enabled, the upstream HO2S signal voltage amplitude and response frequency are checked.
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.
