What does P1136 mean?
intake valve timing control solenoid valve
P1136 Meaning The intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the Engine Control Module (ECM). The intake valve timing control solenoid valve changes the oil amount and direction of flow through the intake valve timing control unit or stops oil flow.
What is a P1137 code?
|P1137 Meaning The Powertrain Control Module (PCM) adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. The HO2S2 generates a voltage between 0.1 and 0.9 V in response to oxygen in the exhaust gas. The PCM interprets Lean when the HO2S2 voltage is below 0.45 V.
What is the code P1131 Ford?
Trouble code P1131 means that the powertrain control module has detected a lean condition for engine bank No. 1. Code P1131 can be caused by a vacuum leak, fuel injector problem, ignition problem or by a faulty oxygen sensor.
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.
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 does the error code P1133 stand for?
This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Buick, Chevrolet, GMC, GM, Toyota, Isuzu, etc. Specification of the definition, troubleshooting, and repairs still vary from one make and model to another.
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.
