What does p1131 mean on an oxygen sensor?
The P1131 means that your upstream oxygen sensor (the one closest to the engine) is not switching rich to lean and back as frequently as it should. This could be due to a vacuum leak, a failing oxygen sensor, or a rich fuel mixture. Things to check for include high fuel pressure,…
What happens if the p1131 code does not return?
If the P1131 does not return, then the connections/wiring issues were most likely your problem. If the P1131 code does return, further testing will be required. We will need to test the Mass Airflow Sensor or MAF sensor, as it is a major airflow input to the PCM.
What causes an error code on a ho2s sensor?
Multiple factors could lead to this error code, such as: Defective HO2S Bank 1 Sensor 1 Open or shorted harness in HO2S Bank 1 Sensor 1 Poor electrical connection in HO2S Bank 1 Sensor 1 Technicians diagnose this code by starting their inspection at the HO2S Bank 1 Sensor 1. They make sure the sensor is working properly.
How much does it cost to diagnose Ford p1131 code?
The cost to diagnose 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 does p1131 stand for on a sensor?
Code P1131 is a manufacturer’s specific code and as such lets you know that diagnosing this condition may be different between manufacturer’s vehicles. In these instances, P1131 will set when the voltage being returned by the sensor is no longer switching above and below approximately .5 volts
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:
How much does it cost to repair a Ford p1131 code?
Start by checking for vacuum leaks. The cost to diagnose 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 I do if my ho2s sensor is not working?
Check the manufacturer’s specifications, as there may be a chart informing you of what the voltage should be at a given RPM. If it fails this test, replace the MAF sensor and retest. If all tests have passed so far, and you continue to get a P1131 code, monitor the HO2S.
