HINT:

When a DTC is output, check the Data List item "Intake Manifold Absolute Pressure" using the GTS.

Refer to DATA LIST / ACTIVE TEST [09/2023 - ]

DTC No.	Intake Manifold Absolute Pressure	Malfunction
P0105-11	Approximately 0 kPa (0 psi)	Short to ground in PIM circuit Short in PIM to EPIM circuit Open in VCPM circuit

If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
