its eiether by your head pipe or somewhere down along the exhaust
Where is the o2 sensor on a Mitsubishi pejero 1999, V6 GDI V75W
Mitsubishi Galant, 2002, 4-cyl, O2 sensor, bank 1 sensor 1 (upstream)... PART NUMBER: MR506364
The O2 sensor bank 1 location on a Mitsubishi Endeavor is next to the top hose of the radiator on the motor. The sensor is slightly below where the top radiator hose connects to the radiator and on the top of the motor.
behind the engine
It screws into the catalytic converter.
No such thing as a O2 Sensor Box. The O2 sensor is located somewhere on the exhaust system. Looks similar to a spark plug with a wire connected. May be more than one. The o2 sensor on my 1990 Mitsubishi Mirage 1.5L (same engine as the colt i believe) is on the exhaust between the manifold and the catalytic converter
That is the pre - cat 02 oxygen sensor.
A defective O2 sensor will not prevent the engine from starting. The engine will start and run albeit not as it should.
There is more than one O2 sensor and they are all threaded into the exhaust system at various points.
You did not specify which O2 sensor it is. Is it sensor 1 bank 1, sensor 2 bank 2, sensor 2 bank 1, or sensor 1 bank 2. There are four O2 sensors on a mazda 626
O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0155 = O2 sensor heater circuit malfunction (Bank 2 Sensor 1). All O2 sensors are threaded into the exhaust system at various points. Bank 2 would be the bank of cylinders that does not contain the #1 cylinder. Bank 2 Sensor 1 would be the first O2 sensor leading from bank 2 of the engine.
