Component Location

General Description

R engine has 4 cylinders though but it is devided to two banks and controlled. Cylinder 1, 4 is included to bank 1 and cylinder 2,3 is bank 2.

DTC Description

P062E is set when the problem of bank2 injector control circuit occurs.

DTC Detecting Condition

Item	Detecting Condition			Possible Cause
DTC Strategy	• Voltage monitoring			• Injector circuit • ECM internal error
Enable Conditions	• Engine running
Threshold Value	• Power stage error for injector voltage control, CPU circuit failure. • Disable to distinguish which cylinder is failed by resulting of multiple of random injectors failure.
Diagnostic Time	• Immediately
Fail Safe	Fuel cut	YES	• -
	EGR Off	NO
	Fuel Limit	NO
	Check Lamp	ON

Specification

Control Type	Component Resistance	Operating Voltage
PIEZO voltage control	150 ~250 kΩ (20℃)	100V ~ 200V(100V ~ 140V at 250bar)
