P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance - 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

PCM compares the difference between MAPS output and calculated MAPS value while enable condition is met.
If the actual MAP value or lower than calculated(threshold) value for 2min failure during tip in - out driving, PCM determines that a fault exists and a DTC is stored.

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.
