DTC P0105-11: Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground [06/2020 - 08/2020]: Description

WARNING: This page is about a different variant/trim than selected.

The manifold absolute pressure sensor detects the intake manifold pressure as a change in voltage. The ECM calculates the intake manifold pressure based on this voltage. The ECM calculates the EGR valve assembly and purge VSV opening amount according to changes in the intake manifold pressure and also detects malfunctions of the manifold absolute pressure sensor using these changes in pressure.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P0105-11	Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground	The manifold absolute pressure sensor output voltage is less than 0.5 V for 0.5 seconds or more (1 trip detection logic).	Open or short in manifold absolute pressure sensor circuit Manifold absolute pressure sensor ECM	Comes on	DTC stored	SAE Code: P0107

HINT:

When this DTC is output, check the intake manifold absolute pressure in the Data List. Enter the following menus: Powertrain / Engine / Data List / Intake Manifold Absolute Pressure.

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 value is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
