DTC P2008 [Z6]

Variable tumble control circuit/open
• The PCM monitors the variable tumble control signal at PCM terminals 2AF
and 2AJ. If the PCM turns the variable tumble shutter valve actuator to open
or close but voltages at PCM terminals 2AF and 2AJ do not coincide with the
PCM signal voltages the PCM determines that the variable tumble control
circuit has a malfunction.
• Variable tumble control IC error.
Diagnostic support note
• This is a continuous monitor (CCM).
