Question about 1992 Jeep Wrangler

1 Answer

1998 Jeep Wrangler Sport codes P0121 and P0122

I have a 1998 Jeep Wrangler Sport. 3 speed automatic transmission and 4.0l inline 6 engine.

I pressure washed the engine compartment the other day(perhaps not this best idea in retrospect) and since then my Check Engine light has been on.

The codes I got are P0121 and P0122

P0121 TPS Voltage Does Not Agree With MAP

P0122 Throttle Position Sensor Voltage Low

I replaced both sensors but the code is still there.

Manifested symptoms are:

engine dies or tries to die when gas pedal is immediately released
coughing and sputtering while driving particularly under load.

What else could it be? I'm at a loss.

po 870 refers to transmission fluid pressure- check fluid level of trans while parked with engine running and the jeep level.- if level is ok- might be time to have filter and fluid changed

95 jeep wrangler: gauge indicates 0 oil pressure


Wire on oil sending unit may have fallen off or sensor itself may have gone bad. Check both. If engine has no tapping noises, likely it's not a pressure problem.

Check engine light codes and troubleshooting


Sounds like you have a vacuum leak for the lean code and the misfires. I don't see a 473 code in my manual, but have a 463. The 463 is for the fuel level sensor open or voltage high.
