Injector Circuit Malfunction

FAULT ID
P0201- P0206

TITLE
Injector Circuit Malfunction Cylinder-1 - Cylinder-6

BACKGROUND
- A surge voltage is generated when the injectors are driven and the current flowing to the injector coil is shut off.
- The engine control module checks this surge voltage.

RANGE OF CHECK
- Engine speed is approx. 50 - 1,000 RPM's
- The throttle position sensor output voltage is 1.15 V or less.
- Actuator test by scan tool is not carried out.

SET CONDITIONS
Surge voltage of injector coil is not detected for 4 seconds.

EFFECT
Limp-in

PROBABLE CAUSES
- Injector failed.
- Open or shorted injector circuit, or loose connector.
- Engine control module failed.
