DTC P2010

DTC P2010 Variable tumble control solenoid valve circuit high input
• PCM monitors variable tumble control solenoid valve control signal at PCM terminal 4T. If PCM turns
variable tumble control solenoid valve on but voltage at PCM terminal 4T still remains high, PCM
determines that variable tumble control solenoid valve circuit has malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
DETECTION
• MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles or in one
CONDITION
drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in PCM memory.
• Poor connection of connectors at PCM and/or variable tumble control solenoid valve
• Short to power circuit in wiring between variable tumble control solenoid valve terminal B and PCM terminal
POSSIBLE
4T
CAUSE
• Variable tumble control solenoid valve malfunction
• PCM malfunction
Diagnostic procedure
STEP
1 PERFORM DTC CONFIRMATION PROCEDURE
• Perform DTC CONFIRMATION PROCEDURE.
(See F–66 DTC CONFIRMATION
PROCEDURE.)
