Calibrated timer to set DTC P0116 has expired. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum. Damaged PCM. Damaged reverse switch An FMEM Strategy called Fail-safe Cooling was activated to cool the engine. This test was designed to protect the transmission. An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault. attack or by an improper shutdown of the computer. Damaged PCM An IMRCM PID reading at closed throttle that is less than VREF may indicate a fault Fuel Delivery Error At least one bank lean at wide open throttle. EVAP Control System Leak Detected (Very Small Leak) The PCM monitors the complete EVAP control system for the presence of a very small fuel vapor leak. High fuel pressure (caused by damaged fuel pressure regulator) NG. Blown fuse Click here follow the steps to fix Ford Fiesta Mk5 Error Codes and related errors. Low engine coolant level. It can also be caused if your computer is recovered from a virus or adware/spyware CASE GND circuit open This condition will cause the boost from the supercharger to be bypassed to avoid potential engine damage. EGRVR circuit short to VPWR or GND Failure of this ECU can be a common occurrence for the Ford Fiesta 1.4 litre engine from 2002 to 2008 faults that we find are a misfire on two cylinders or complete non starting.
