SOURCE: P0154 Trouble Code on my 2002 Mitsubishi Montero Sport. Where exactly is the bad 02 sensor? There are four of them and I don't know which one is the Bank 2 #1 sensor.

Bank 2 is the side of the engine with cylinder number 2, and sensor one is the sensor in front of the catalytic converter.
Please know that the code does not mean the sensor is bad, only that the reading the computer is getting is constantly lower than .3 volts.
The sensor could be faulty, or there could be a problem with the fuel injectors or the wiring harness to the sensor.
When the sensor is working correctly, the reading should switch back and forth between .3 and 1.0 volts.

Code p0154


P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)

Check for the following:

Backed out terminals
Improperly formed or damaged terminals
Poor terminal to wire connection
Damaged harness

2. A malfunctioning HO2S heater on heater circuit

Ive got a question for a 1997 chevy tahoe. i need to find out which o2 sensor to change when a DTC codes register with P0155 AND P0154. can anybody help me?


P0155 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
THIS IS THE SENSOR BEFORE THE CAT CONVERTER
P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
SAME SENSOR, WHEN THEY SAY BANK 2 IT IS THE BANK OF CYLINDERS OPPOSITE THE BANK THAT HAS #1 CYLINDER IN IT,
MAKE SURE THE SENSOR IS CONNECTED AND THAT THE CONNECTOR IS NOT DAMAGED.
