2010 Cadillac Truck SRX FWD V6-3.0L Page 1127
Circuit Description
The manifold absolute pressure (MAP) sensor has a 5 V reference circuit, a low reference circuit, and a signal circuit. The engine control module
(ECM) supplies 5 V to the MAP sensor on the 5 V reference circuit, and provides a ground for the low reference circuit. The MAP sensor provides
a voltage signal to the ECM on the signal circuit relative to the intake manifold pressure changes.
Conditions for Running the DTC
* DTC P0697 is not set.
* The engine is running.
* This DTC runs continuously within the enabling conditions.
Conditions for Setting the DTC
P0107
The ECM detects that the MAP sensor voltage is less than 0.20 V for more than 5 s.
P0108
The ECM detects that the MAP sensor voltage is more than 4.80 V for more than 5 s.
Action Taken When the DTC Sets
DTCs P0107 and P0108 are Type B DTCs.
Conditions for Clearing the MIL/DTC
DTCs P0107 and P0108 are Type B DTCs.
