P0158 Engine Code Repair
Meaning of P0158 engine trouble code is a kind of powertrain 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.
P0158 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for P0158 code is occuring now you should check P0158 repair processes.
Now don't ask yourself; What should you do with P0158 code ?
The solution is here :
P0158 Possible Solution:
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.
P0158 Code Meaning :

0
Intake Valve Control Solenoid Circuit Low
1
Ambient Air Temperature Sensor Circuit Low
5
Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector)
8
Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical
Regarding the P0158 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.
P0158 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0158 OBD-II Trouble Code The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. For optimum catalyst operation, the air fuel mixture (air-fuel ratio) P0158 code.Main reason For P0158 CodeThe reason of P0158 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low. |
Parts or components should not be replaced with reference to only a P0158 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
