DTC P0201: Injector Circuit Malfunction - Cylinder 1, DTC P0202: Injector Circuit Malfunction - Cylinder 2, DTC P0203: Injector Circuit Malfunction - Cylinder 3, DTC P0204: Injector Circuit Malfunction - Cylinder 4, DTC P0205: Injector Circuit Malfunction - Cylinder 5, DTC P0206: Injector Circuit Malfunction - Cylinder 6

CIRCUIT OPERATION
• The injector power is supplied from the MFI relay (terminal No. 1).
• The PCM controls the injector by turning the power transistor in the PCM "ON" and "OFF".
TECHNICAL DESCRIPTION
• The amount of fuel injected by the injector is controlled by the amount of continuity time the coil is grounded by the PCM.
• A surge voltage is generated when the injectors are driven and the current flowing to the injector coil is shut off.
• The PCM checks this surge voltage.
DESCRIPTIONS OF MONITOR METHODS
Off-surge does not occur after injector is operated.
MONITOR EXECUTION

Refer to Diagnostic Function - OBD-II Drive Cycle - Procedure 6 - Other Monitor .
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:
• Injector failed.
• Open or shorted injector circuit, or harness damage or connector damage.
• PCM failed.
