00 Jeep Grand Cherokee P0130, P0136, P0152, P0158
My 2000 Jeep Grand Cherokee (4.7l) had the famous dieing out while driving issue, after many hours of research it seemed replacing the PCM would have highest chance of fixing it. I ordered a rebuilt one and installed it, and the Jeep has not stalled since then. I now have ODB codes P0130, P0136, P0152, P0158, figured the O2 sensors may have died and the old PCM was that out of wack they never alerted. I replaced both O2 sensors in the Jeep and erased all the codes. The same codes are back, so now I am stuck trying to figure out what would cause all 4 of those codes to alert at the same time. If the PCM was programmed for Cal emissions would those codes alarm? I am going through the engine today to make sure cables have not been shorted out anywhere. Also replacing the spark plugs and going with a good tuneup.
clear this up - is this vehicle- check radiator tag- CALIFORNIA emissions? and was the same PCM (national or calif) used? Calif has 4 o2 sensors... the 2 codes P0130 and p0136 - not familiar with so will look it up and add later preliminary says a ASD issue need to check that... The other codes P0150 and P0158, both for post cat o2 sensor shorted to voltage... you did replace the o2 sensors? did you use jeep or aftermarket parts? I think if we clear up 2 or 4 o2 sensors and if AFTERMARKET or OEM...will help USE ONLY OEM type plugs, sensors, - filters, etc.
