SOURCE: Service engine lights comes on for awhile and goes

You typically would like to do further diagnosis, however on these cars, the Denso sensors are very common to fail, and are the cause of the light 99% of the time, especially if it is the only code set.

Bank 2 sensor 1 is located on the top of the exhaust manifold on the radiator side of the engine. You will need an O2 sensor socket or a small 22mm wrench to remove it

P0155 error code Mitsubishi diamante 2002 where is it located the sensor


P0155 is not telling you which part is defective, it is saying there is a problem in the system and that the triggers the fault code. In this case you have a O2 sensor whose heater is not heating. This may be the senor or the wiring to it.
P0155 OBD-II Trouble Code: 02 Sensor Heater Circuit Malfunction in cylinder Bank 2 (V6 only), Sensor 1, this is the sensor before the catalyst.

P0123, p0155, p0306


Well it really doesn't matter much. I would probably clear the codes and see which ones come back first.
Code 123 is for the throttle position sensor signal being out of range. Could be the sensor or a wiring problem.
Code 155 is for a problem with the heater circuit going to O2 sensor bank 2 sensor 1. Thats on the side with cylinder two if you have a V6 engine. Could be the sensor but its usually the lack of power for the heater.
Code 306 is for loss of power from cylinder 6 which could be mechanical, fuel, or spark related.
The three codes are not connected to each other. And trouble codes are not a statement to replace parts, only what to test.

Code P0155, 1155, will get those code's with vacuum leaks, I have seen that many times here at my repair shop, many times customers come in, after they have done a tune-up, as you have, and same problem, check for vacuum leaks, more so on top of engine to the back, by fire wall.
