DTC P1144 (PS_RHI): Pressure Sensor Circuit Range/Performance Problem (High Input)

Turn ignition to off. Connect SSM. Turn ignition and scan tool on. Start engine. Select SSM function mode F20 to read signal value from pressure sensor. If sensor value is more than 133 kPa, replace sensor. If sensor value is less than 133 kPa, circuit is normal. Check for poor contacts at connectors.
