2.31 DTC P1151 (44), P1152 (44)
GENERAL
Bank Angle Sensor
The Bank Angle Sensor (BAS) operates from the ECM 5 volt
sensor reference, and is grounded through the ECM on a
common sensor ground circuit. Refer to
Table 2-63 . The BAS
sends a signal to the ECM ranging from 0.24 - 3.4V under
normal operating conditions. A signal between 3.4 - 4.79V will
cause the ECM to turn off the engine. Once activated, the BAS
causes the ECM to turn off the engine. When the vehicle is
righted, the ignition must be switched OFF and then ON in
order to restart the engine.
If the signal from the BAS is below 0.24V or above 4.79V, the
ECM sets a code. Refer to
Table 2-62 . DTC P1151 is set when
the BAS output is shorted low (to ground); and P1152 is set
when the BAS output is shorted high (to voltage). An open
circuit output will act like a shorted high, and set DTC P1152.
If a code occurs, the engine will continue to run.
A tipped vehicle will not set a DTC.
