codes
Hi all,new to the forum here but ive been reading posts alot.
i have two codes that im wondering what to do with first is p0155 and second is p1151.Seems that both have to do with the 02 sensor but im not sure if i should go buy one or get a "dummy" one that my buddy told me about .he said that sometimes on the 02 sensors after the cat i might b able to get a "dummy" one.any help would be greatly appreciated.
thank you ,alawens

P0155 AND P0161: HO2S HEATER CIRCUIT IS OPEN, SHORTED TO GROUND, SHORTED TO VPWR OR EXCESSIVE CURRENT DRAW, LOW CURRENT DRAW
this would be a wiring problem i would inspect around the area above the tranny and between the body that would be a likely spot for it to rub or pull apart.
P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTCs P1130 and P1150: FUEL SYSTEM NOT SWITCHING AT FUEL TRIM (RICH OR LEAN)
Check intake air system for leaks, obstructions and damage.
Check air cleaner element, air cleaner housing for blockage.
Verify integrity of the PCV system.
Check for vacuum leaks. if its none of these it goes into testing the MAF sensor.
just incase you typed the P1151 code wrong here is what you do for a P0151 which is more O2 sensor related
CHECK FOR SOURCE OF POTENTIAL HO2S CONTAMINATION
Investigate the following items as potential sources of HO2S contamination:
Use of unapproved silicon sealers.
Fuel contaminated by silicon additives.
Excessive oil burning (i.e. rings, valve seals and oil overfill).
Glycol (antifreeze) leaking internally in the engine.
Lead contaminated fuel.
Short drive cycles in cold weather.
Use of unapproved cleaning agents.
then most likely replace an O2 sensor and they recomend oil change at same time.
please disreguard the caps lock i wasn't yelling.
