Section 8.7
SPN 164/FMI 7

This SPN indicates there is high pressure pump leakage or the TDC position is wrong (MU341). The fault condition is typically related to a pump that is out of time by +/- 6 degrees or high pressure pump plunger failure. The MCM monitors rail pressure rise and timing then compares it to a calibrated value. ‪
