E16D8AB6
As monitoring the errors of several sensors and actuator circuit, TCM related problem and ECM error, if any problem
occurs, ECM turns Engine Check Lamp ON at cluster to notify driver the occurence of a problem.Generally, Engine Check
Lamp turns ON at Ignition ON and turns OFF within couple of seconds after turning engine ON. If engine check lamp
turns on during driving, perform diagnosis of engine system and auto-transaxle system.
DTC DESCRIPTION
E77C406A
P0652 is set when the voltage below 4.7V - minimum voltage of sensor power supply 2 generates from ECM - is detected
for more than 0.1 sec.. This code is due to the short to ground in sensor power circuit or the voltage problem inside of
ECM.
