P1135 Code – General. OBD-II code P1135 represents a general fault in the air/fuel sensor heater circuit for bank 1, sensor 1. The sooner the air/fuel ratio sensor gets to that minimum temperature, the quicker the sensor will begin to send accurate signals to the ECM, or engine control module.Click to see full answer. Also asked, what is p1130 code?The 1130 code is set when A/F sensor output voltage change value is not what the Engine Control Module (ECM) is expecting.Likewise, what is a air fuel ratio sensor? The air fuel ratio sensor is installed in the exhaust manifold or in the front exhaust pipe, before the catalytic converter. The job of the air fuel ratio sensor is to measure the oxygen content in the exhaust and provide feedback to the engine computer (PCM). Similarly, you may ask, what does p1155 code mean? OBD-II code P1155 represents a malfunction in the air/fuel sensor heater circuit for bank 2, sensor 1. The air/fuel ratio sensor on your vehicle has to reach a particular operating temperature to produce accurate voltage signals.What is p1131 engine code?Ford Code P1131. by Robert Moore. 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.
