DTC P0107: Manifold Absolute Pressure / Barometric Pressure Circuit Low Input; DTC P0108: Manifold Absolute Pressure / Barometric Pressure Circuit High Input: Description

The manifold absolute pressure sensor detects pressure inside the intake manifold as an absolute pressure with a built-in sensor and outputs a voltage. Based on the voltage from the vacuum sensor, the hybrid vehicle control ECU controls the purge VSV and corrects any errors in the pressure sensor due to changes in pressure.

DTC No.	DTC Detecting Condition	Trouble Area
P0107	The output voltage from the manifold absolute pressure sensor is less than 0.5 V for 0.5 seconds. (1 trip detection logic)	Open or short in manifold absolute pressure sensor circuit Manifold absolute pressure sensor Hybrid vehicle control ECU
P0108	The output voltage from the manifold absolute pressure sensor is more 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 Hybrid vehicle control ECU

HINT:

When DTC P0107 or P0108 is detected, check the manifold absolute pressure by selecting Powertrain / Engine and ECT / Data List / MAP on the Techstream.
