U2394 Engine Code Repair
Meaning of U2394 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.
U2394 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for U2394 code is occuring now you should check U2394 repair processes.
Now don't ask yourself; What should you do with U2394 code ?
The solution is here :
U2394 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.
U2394 Code Meaning :
U
OBD-II Diagnostic Network (U) Trouble Code For Engine
2
Fuel And Air Metering (Injector Circuit Malfunctions Only)
3
Manifold Absolute Pressure/Barometric Pressure Circuit High Input
9
Ignition/Distributor Engine Speed Input Circuit Malfunction
4
Exhaust Gas Recirculation Sensor B Circuit High
Regarding the U2394 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.
U2394 OBD-II Diagnostic Network (U) Trouble Code DescriptionU2394 engine trouble code is about Exhaust Gas Recirculation Sensor B Circuit High.Main reason For U2394 CodeThe reason of U2394 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input. |
U2394 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.
