Circuit/System Testing



1. Ignition OFF, disconnect harness connector of the B47 fuel pressure sensor.



2. Ignition OFF, test for less than 1.0 ohm between the low reference circuit terminal 2 and ground.



瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K27



fuel pump control module.



3. Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal 3 and ground.



瀚慖f less than the specified range, test the 5 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal,



replace the K27 fuel pump control module.



瀚慖f greater than the specified range, test the 5 V reference circuit for a short to voltage. If the circuit tests normal, replace the K27 fuel



pump control module.



4. If all circuits test normal, replace the B47 fuel pressure sensor.
