P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input - General Information

Component Location





General Description

PCM compares the MAPS output and calculated MAPS value while enable condition is met. If the acutal MAP value is higher than Maximum threshold or lower than Minimum threshold for a pre-determined time, PCM determines that a fault exists and a DTC is stored.

DTC Description

If sensor signal input is higher than 4.85V during 0.1sec, PCM sets DTC P0108.

Signal Waveform & Data




As often as possible, the MAPS signal should be compared with the TPS signal. Check whether the MAPS and TPS signals increase at the same time when accelerating. During acceleration, the MAPS output voltage increases; during deceleration, the MAPS output voltage decreases.
