When you check car engine light came on code P1777 the reason should be Engine Light ON (or Service Engine Soon Warning Light). P1777 Fault Symptoms :
If one of these reasons for P1777 code is occuring now you should check P1777 repair processes. Now don’t ask yourself; What should you do with P1777 code ?

In later car models, the car’s computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. P1777 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP1777 engine trouble code is about Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical. Reason For P1777 CodeThe reason of P1777 OBD-II Engine Trouble Code is Fuel Rail Pressure Sensor Circuit Malfunction. Parts or components should not be replaced with reference to only a P1777 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Adblockdetector |
