The manifold absolute pressure sensor detects pressure inside the intake manifold as an absolute pressure with a built-in sensor and outputs it as voltage. Based on the voltage from the manifold absolute pressure sensor, the ECM controls the purge VSV and corrects any errors in the air fuel ratio due to change in pressure.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory	Note
P0107	Manifold Absolute Pressure / Barometric Pressure Circuit Low Input	The output voltage from the manifold absolute pressure sensor is less than 0.5 V for 0.5 seconds (1 trip detection logic).

HINT:

When any of these DTCs are output, check the manifold absolute pressure using the Techstream. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.

MAP	Malfunction
Approximately 0 kPa (0 psi)	Short to ground in PIM circuit to ground Short in PIM circuit to EPIM circuit Open in VCPM circuit
130 kPa (18.85 psi) or higher	Short in VCPM circuit to PIM circuit Open in PIM circuit Open in EPIM circuit
