P3148 Engine Code Repair
Meaning of P3148 engine trouble code is a kind of powertrain trouble code and when the check engine light comes P3148 code on the first you should check is the gas cap. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Continue driving and see if the check engine light turns off.

P3148 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for P3148 code is occuring now you should check P3148 repair processes.
Now don't ask yourself; What should you do with P3148 code ?
The solution is here :
P3148 Possible Solution:
Air Conditioning Pressure Sensor (ACP) Insufficient Pressure Change Each time the A/C clutch engages, the PCM is looking for a pressure change in the refrigerant. If the change in pressure is outside of the calibration the DTC will set. A/C system mechanical failure Open ACP or VREF circuit A/C sensor damaged A/C system electrical failure A/C clutch always engaged Verify A/C system function, including refrigerant charge.
P3148 Code Meaning :
P
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine
3
Ignition System Or Misfire
1
Ambient Air Temperature Sensor Circuit Low
4
Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)
8
Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical
The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.
P3148 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP3148 engine trouble code is about Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical.Main reason For P3148 CodeThe reason of P3148 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low. |
P3148 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
