Typical Engine Control Unit (ECU) Monitor Malfunction Thresholds:P0600 – – A data transfer between chips in the ECU either is not possible or has invalid check bytesOR Communication is interrupted between the CPU and the monitoring moduleP0601 – An error is detected in the post-drive ROM testP0606 – A powerstage shutoff command is active OR A communications error exists between the powerstagecontroller chip and the CPUP0607 – A software reset is detected by the ECUP060A – An irreversible error occurs with an operating system function call OR An irreversible error occurs inthe test of the monitoring moduleP060B – Failure on power-up calibration done for the A/D conversion module and A/D conversion timeperformed on ECU start OR >249 mV reading in the cycle following grounding of a specific voltage OR Cyclicalconversion of a predetermined voltage results in 4830 mV reading.P060D – If either pedal voltage 1 or pedal voltage 2 < 742 mV and (pedal voltage 1) – 2 * (pedal voltage 2) >547 mV OR If pedal voltage 1 and pedal voltage 2 >= 742 mV and (pedal voltage 1) – 2 * (pedal voltage 2) >1055 mVP0611 – If the raw voltage detected by an internal ECU voltage measurement for fuel system Nominal VoltageCalibration falls below 0 mV or above 3300 mV for the monitoring durationP061A – Commanded inner torque > permissible inner torque at current engine operating conditionP061B – The energizing time for Zero Fuel Calibration is 850 ms (beyond limits for P02CC-P02DA) OR The difference between programmed energizing time and actual energizing time exceeds 127.2 usor The requested time for start of energizing of a given fuel injection is outside the crank angle regime permittedfor that injectionOR The correction in requested fuel injection quantity due to transient pressure effects within the fuel injector ascalculated by the control software and as calculated by the monitor exceeds 5 mg for an injectionP061C – The engine speed calculated by the control software and the engine speed calculated by the monitordeviate by more than 400 RPMP062B – If an error is detected in a requested post injection OR If requested energizing time exceeds 200 uswhen the controller is operating in overrun/decel fuel shut-off modeP062F – An error is detected in an EEPROM read, write, or erase operationP06A6 – Voltage output of sensor supply 1 is 5.3 VP06A7 – Voltage output of sensor supply 2 is 5.3 VP06A8 – Voltage output of sensor supply 3 5.3 VP167F – a non-OEM calibration has been detectedP2506 – If an unexpected loss of power that resets the main ECU relay occurs OR If the main ECU relay isactive for more than 150 ms and battery voltage > 9VP2507 – The 5V internal ECU supply is 5.5 VP2610 – If, during a key off event, engine coolant temperature decreases by 30 degrees and the engine offtimer has not incremented at least 1200 seconds OR If, while running for 1200 seconds as measured by ECUtimer, the timer used for engine off time and the time as determined by the secondary timer differ by at least 100seconds OR In afterrun, if a requested 8 second stop timer measurement is 8.48 secondsFORD MOTOR COMPANY REVISION DATE: FEBRUARY 9, 2012 09.01.00.02-PAGE 132 OF 157
