If your vehicle is not a diesel, you likely have a fault with one of the other components listed above. While the sensor is often the culprit, it is also possible for the problem to be completely unrelated to the sensor wiring harness, connections, etc. If that code is no longer there, it can only be a result of somebody clearing the computer memory.
So you should chech it on our car models. . I would rather be sailing this could be 1 of a few faults, Spill valve on injection pump Spill valve relay Fuel pump ecu which i would guess at being the fault Main engine ecu Diesel pump its self but unlikely. So you should chech it on our car models. Regardless of how you approach it, you should get this fixed right away. Overhead cam engines are especially at risk, because the cam and valve train are farther from the pump than they are in pushrod engines.
The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. People often ask us for advice regarding problems they are having with the Vauxhall 1. You should also check that the spark plug gap is set properly. What does fault code P0251 mean?

P0126 coolant temp insufficient for stable operation. Note also that although this particular system employs an electric lift pump in the fuel tank, not all applications are so equipped. Ford has had a lot of trouble with these. You can check operation of most sensors if you have a code reader that can display live data. A faulty crank sensor will stop the ecu and edu from working so no fuel flows to injectors. Spark plugs typically need to be replaced every season or 25 hours of use.
What repairs can fix the P0251 code? If engine now runs, check for damaged connectors, broken wires or possible ecu fault. If nothing is found wrong with the harness, the connections will be checked.
