Failed OBDII Diagnstic trouble codes P0761 and O1744 What does this mean?


code P0761-
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 3 valve
- Shift solenoid 3 valve harness or connectors
- Shift solenoid 3 valve circuit is open or shorted
P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

Yes my truck is 1998 ford f 150 4.2 an i have code po174






DTC code p0174 means "System too lean (Bank 1)"

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exahust). On V6/V8/V10 engines



, Bank 2 is generally the side of the engine that doesn't have cylinder #1.

Check engine light codes P0174, P0105


P0174, refers to a lean condition of the engine....Possible causes would be a vacuum leak, clogged fuel filter, or a leaking intake gasket( this is the most likely cause because Jaguar has a service bulletin on this very issue). P0105, refers to a MAP sensor malfunction which could also be causing the P0174
