Circuit Description

During calibration of offset of pressure sensor signal, pressure sensor signal offset value must be -217.5 to 217.5 psi (-5.29 to 5.29 kg/cm² ). Pressure sensor is also monitored for sensitivity via a correlation between estimated vehicle deceleration and pressure sensor signal. This is monitored over the course of numerous straight line non ABS braking stops.

DTC sets when sensor signal offset value is out of range for more than one second with brake pedal applied, ABS pump is not on and vehicle speed is greater than 25 MPH.
