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.

Jeep grand cherokee p0155 code p1494


For the P0155 code, check the fuse for the O2 heater circuit.
The P1494 has to do with the EVAP leak detection pump pressure switch. Or the switch is faulty, or there is a large leak. Do you hear any hissing sounds under the jeep?
