Speed and Idle Control (DTC) Index

DTC	Error Message	Diagnostic Procedure	Malfunction Criteria and Threshold Value	Secondary Parameters with Enable Conditions	Monitoring Time Length	Frequency of checks, MIL Illum
P0501	Vehicle Speed Sensor A Range/Performance	-- Check vehicle speed signal. Refer to SPEED SIGNAL, CHECKING .	VSS signal, < 4 km/h	engine torque >150 Nm Engine speed, >2500 RPM vehicle speed sensor, no fault	5 Sec	multiple 2 DCY
P0503	Vehicle Speed Sensor A Out of range high	-- Check vehicle speed signal. Refer to SPEED SIGNAL, CHECKING .	vehicle speed > 200 km/h	---	0.5 Sec	Continuous 2 DCY
P0506	Idle Air Control System RPM Lower Than Expected	-- Check the Throttle Valve Control Module -J338-. Refer to THROTTLE VALVE CONTROL MODULE, CHECKING .	engine speed deviation <-80 RPM AND RPM controller torque value>= calculated max. value integrated deviation of engine speed low and integrated deviation of engine speed high> 2000 RPM	driver torque demand, none Vehicle speed, 0 MPH engine speed idle Altitude, < 2700 m EVAP purge adaptation< 22.00 external torque request, not demanded lambda control active	3 Sec	multiple 2 DCY
P0507	Idle Air Control System RPM Higher Than Expected	-- Check the Throttle Valve Control Module -J338-. Refer to THROTTLE VALVE CONTROL MODULE, CHECKING .	engine speed deviation >-80 RPM AND RPM controller torque value<= calculated min. value	external torque demand, none engine speed 0 RPM Vehicle speed, 0 MPH Altitude, < 2700 m EVAP purge adaptation< 22.00 lambda control active	7 Sec	multiple 2 DCY
P050B	Cold Start Idle Air Control System Performance	-- Check the Throttle Valve Control Module -J338-. Refer to THROTTLE VALVE CONTROL MODULE, CHECKING .	difference between commanded spark timing vs. actual value> 0.25%	time during catalyst heating> 13 Sec commanded spark retard during catalyst heating< 70% catalyst heating active	0.5 Sec	once/DCY 2 DCY
P052A	VVT Actuator Intake	-- Check the Camshaft Adjustment Valve 1 -N205-. Refer to CAMSHAFT ADJUSTMENT VALVE 1, CHECKING .	difference between target position vs. actual position > 12.0 °CRK	time after engine start>= 15.0 Sec modeled oil temperature>= -13° C catalyst heating active	3.5 Sec	Once/DCY 2 DCY
P053F	Fuel Rail Control Valve, high pressure side	-- Check the Fuel Pressure Sensor -G247-. Refer to FUEL PRESSURE SENSOR, CHECKING .		time after engine start 12.0 Sec fuel cut off not active catalyst heating active	3.5 Sec	multiple 2 DCY
