DTC P2010[L3 WITH TC]

DTC P2010 Variable swirl solenoid valve control circuit high
• PCM monitors the variable swirl solenoid valve control signal. If the PCM turns variable swirl solenoid valve
on but the voltage still remains high, the PCM determines that the variable swirl solenoid valve control
circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
DETECTION
• MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in
CONDITION
one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive
cycle.
• FREEZE FRAME DATA is available.
• DTCs are stored in PCM memory.
• Poor connection of connectors at the PCM and/or the variable swirl solenoid valve
• Short to the power supply in the wiring harness between variable swirl solenoid valve terminal B and PCM
POSSIBLE
