U2988 Engine Code Repair

Meaning of U2988 engine trouble code is a kind of network trouble code and theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $240-$400 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

U2988 Fault Symptoms :

  1. Check engine light comes on
  2. Engine stalling or misfiring
  3. Engine performance issues
  4. Car not starting

If one of these reasons for U2988 code is occuring now you should check U2988 repair processes.
Now don't ask yourself; What should you do with U2988 code ?
The solution is here :

U2988 Possible Solution:

U2988 Engine

Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

U2988 Code Meaning :

U
OBD-II Diagnostic Network (U) Trouble Code For Engine

2
Fuel And Air Metering (Injector Circuit Malfunctions Only)

9
Engine Oil Temperature Sensor Malfunction

8
Cylinder 10 Contribution/balance Fault

8
Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical

Regarding the U2988 code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket. This is done most easily from below the car in the area near the oil filter.

U2988 OBD-II Diagnostic Network (U) Trouble Code Description

U2988 engine trouble code is about Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical.

Main reason For U2988 Code

The reason of U2988 OBD-II Engine Trouble Code is Engine Oil Temperature Sensor Malfunction.

U2988 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
