DTC P0106: MAP SYSTEM PERFORMANCE (2.4L "N" BODY) Saturn SL II

Testing & Diagnostics ~148 words

Note. For circuit reference, see appropriate wiring diagram in WIRING DIAGRAMS article.

Circuit Description

Powertrain Control Module (PCM) supplies a 5-volt reference signal and a ground circuit to Manifold Absolute Pressure (MAP) sensor. As manifold pressure changes, monitored MAP sensor signal voltage changes. PCM compares detected sensor voltage changes to a predetermined value set by PCM. If PCM does not see expected value, DTC P0106 will set.
