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 errors in the manifold absolute pressure sensor using these changes in pressure.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Memory
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 or more (1 trip detection logic).	Open or short in manifold absolute pressure sensor circuit Manifold absolute pressure sensor ECM	Comes on	DTC stored
P0108	Manifold Absolute Pressure / Barometric Pressure Circuit High Input	The output voltage from the manifold absolute pressure sensor is higher than 4.5 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

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.

Pressure Displayed	Malfunction
Approximately 0 kPa (0 psi)	Short in PIM circuit to ground Short in PIM circuit to EPIM circuit Open in VCPM circuit
130 kPa (19 psi) or higher	Short in VCPM circuit to PIM circuit Open in PIM circuit Open in EPIM circuit

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