C1993; PRESSURE SENSOR SIGNAL CIRCUIT FAULT

G256924t65: CHECK THE PRESSURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
1. Disconnect the pressure sensor electrical connector, CR92.
2. Measure the resistance between CR92, pin 02 (G) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t66: CHECK THE PRESSURE SENSOR SIGNAL CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the ASU electrical connector, CR90.
3. Measure the resistance between CR92, pin 02 (G) and CR90, pin 14 (G).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
-> No
INSTALL a new valve block, CLEAR the DTC. TEST the system for normal operation.
