Essentially the same as P0136 Ford and P0137 Ford, a P0131 Ford code definition:the first oxygen sensor on Bank 1. See P2195. 1 Unplug the right front O2 (HO2S11) sensor from the engine wiring harness connector and place your multimeter in Volts DC mode. And: P1151 - Lack of HO2S21 Switches - Sensor indicates lean. 7L V6 EcoBoost Fuel injectors (under the intake manifold) Fuel Injection pump (under cover at rear of Here's the exact codes my tuners diagnostics is reading: P1131 - Lack of HO2S11 Switches - Sensor indicates lean. The P0031 Nissan code refers to the heater control circuit low for the HO2S11 sensor, also known as the Bank 1 Sensor 1 oxygen sensor. The HO2S11 sensor is the Heated Oxygen Sensor located in the exhaust system, near the catalytic converter. In this tutorial, I'll explain how to test the front oxygen sensor (HO2S 11) heater on the 1998, 1999, 2000, or 2001 2. 4L car (pick up, SUV) is not that hard to do. Learn what HO2S11 Sensor Circuit Low Voltage means, location and how to repair. Below is a description of the wires of the right front oxygen sensor (HO2S11): NOTE: The right front oxygen sensor is located on the right side (passenger side) of the engine. It's the O2 Camshaft position sensors (CMP) (located at the front of the driver side cylinder head) Heated Oxygen Sensor HO2S11 (located in the passenger side exhaust Learn what HO2S11 Sensor Heater Circuit means, location and how to repair. This sensor 5. 2017 Ford F150 2. 1) it is on a 99 mercury cougar v6 i need to know exactly where this o2 sensor is located. there is three or four of them depending if you have dual pipes or a single exhaust pipe. -kyle ryno- HO2S11 Sensor Location Repair Common Mistakes P2196 Code Your Ford cars can have a DTC indication if problems Repair Information for P0135 Volkswagen code.
