HI I HAVE 2004 F 150 4.6 AUTOMATIC 2WD AND I HAVE THIS CODES P0146 P0155 AND P0962?


146 is the oxygen sensor AFTER the catalytic converter. Check the exhaust system for leaks and check the wiring to the sensor, don't just replace the sensor. 155 is the heater circuit for the oxygen sensor, Check the wires and fuses the last code is for the transmission. did you run over something and damage the undercarrige

I have a 1998 Deville and the pcm P0155 code is current and the car is overheating and no air comes out the vents on any setting! Please help?


Well, code 155 for the engine computer means there is a problem with the heater circuit for the O2 sensor. That sensor is in the exhaust pipe and would have nothing to do with the heater inside the car.
Have you checked to make sure the cooling system is full of liquid coolant ?

Wheret is the heater circuit?


P0155 is an O2 sensor heater circuit problem Bank 2 sensor 1. Replace the O2 sensor closest to the engine on the passenger side. The heaters are built into the sensor. No repairing them.

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.

Error codes po 134 po 153 po 154 po 155 po 171 po 174


PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS
