DTC No.	DTC Detection Condition	Trouble Area
P0107	The manifold absolute pressure sensor voltage is below 0.5 V for 0.5 seconds (1 trip detection logic).	Open or short in manifold absolute pressure sensor circuit Manifold absolute pressure sensor ECM
P0108	The manifold absolute pressure sensor voltage is higher than 4.5 V for 0.5 seconds (1 trip detection logic).	Open or short in manifold absolute pressure sensor circuit Manifold absolute pressure sensor ECM

HINT:

When either of these DTCs is 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	Short in PIM circuit to ground Open in VC circuit
130 kPa or higher	Short in VC circuit to PIM circuit Open in PIM circuit Open in E2 circuit
