What is the meaning code p 0138? - Grand Cherokee Jeep Cars & Trucks

code p 420 refers to cat converter system , bank 1--efficiency below threshold ===causes ---cat converter faulty---wiring --heated oxygen sensor (HO2S), 2 faulty
code p 0134 refers to HO2S 1 bank 1-no activity detected ===causes --wiring open circuit -- heating inoperative --- HO2S
also refers to oxygen sensor ( O2S) 1 bank 1--no activity detected == causes wiring ---O2S
code p 0138 refers to HO2S 2 bank 1--high voltage === causes ---wiring short to positive ---HO2S--- ECM
also refers to O2S 2 bank 1 high voltage === wiring short to positive O2S -- ECM
I do not have a listing for code p 1338 but I suspect that it will refer to the other codes in some way
first fix is to check the cat converter is operational ( not cracked and blocking the exhaust system)
next replace the HO2S sensor ( one before the cat converter ) and then the O2 sensor (the one after the cat converter)
all the codes will relate to problems in that area

okay, 1998 voyager these are not obd2 codes, these are genric codes, you used ignition to get these .
these codes are for older models that use codes like these 12 35.
the newwer obd 2 use codes like po 013. i will try to see what i can find, also the engine size is important.

okay here we go, the first code is 12, this code means the battery was dead or dissconnected.
the next code 35. this code means loss of prime, code # 11
means internal transmission failure.
the code 55 means gear ratio error.

these codes would tell me that you have transmission problems. this may mean internal trans failure and a rebuild or replacement transmission is needed or shift pack needs replacing. anyhow i would have a shop check this out, these van are known for transmission problems. hope this is helpful good day

A code P0138 may mean that one or more of the following has happened:

• Faulty O2 sensor
• Short to battery voltage in O2 sensor signal circuit
• High fuel pressure (not as likely)

you can get a code scan tool to clear the fault code

This may help you diagnose the problem

Your timing is off and an O2 sensor issue. The timing is your big problem though. Thats whats making your car run bad. Basically you need to realign timing belt. Probably won't need to buy anything unless your timing belt is off. Unless your mechanically inclined I wouldn't attempt to set your timing

code p 0138 refers to 2 items
1--heated oxygen sensor(HO2S) 2 bank 1--high voltage ==causes --wiring short to positive --HO2S---ECM
2--oxygen sensor (O2S) 2 bank 1--high voltage ===causes wiring short to positive ---ECM
code p 0139 refers to 2 items
1--- heated oxygen sensor (HO2S) 2 bank 1--slow response ===causes --heating inoperative --wiring--ECM
2--oxygen sensor (o2S) 2 bank 1 slow response ===causes --wiring --- O2S

heated oxygen sensors9HO2S) are in the exhaust manifold before the cat converter
Oxygen sensors (O2S) are after the cat converter
it is indicated that the HO2S is faulty-
check the wiring and /or replace both sensors
