DTC ) fault code ) - P1237:
Boost Control Positive Deviation

This fault code can be set when the fuel tank is empty or the specified fuel is not used. ( supermarket fuels etc have been known to cause this.. )

It can also be attributed to a turbo fault - if the fault is no turbo boost.

Connect a scan tool to the car and check for DTC codes. If the car stalls likely a check engine code is set.

Your friendly auto parts stores will provide this as a complementary service.

First scanned the PCM (computer) to know exactly what fault code is stored there; when check engine light come on, some fault code is there.

Fault codes generally start with a P and P1963 is an invalid fault code. Fault codes for Ford/Lincoln/Mercury do start with P1XXX however.

It means that it is switching to limp home mode, the computer has detected an engine problem, you need to get a code reader or take it to somone who has one and read out the fault codes to see what is faulty/needs replacing.

go to autozne and get a free computer scan to see what fault code you have stored. fix fault, then disconnect battery for 2 hours to clear code and light.

it is quite important, you are in emergency get home mode the light means your engine management system has detected a fault you will need to take it into a garage to get the fault looked up properly and repaired however if you are a DIY mechanic you require a fault code reader to read the fault code from the ECU
