* Broken, clogged or restricted flex tubes, primary fuel tank module

* Broken, clogged, disconnected, or restricted fuel transfer tube inside tank

瀚慖f you find any of the above conditions, repair as necessary.

7. If all circuits/connections test normal, test or replace the left/secondary fuel level sensor.

Component Testing

1. Ignition OFF, remove the left fuel level sensor from the fuel tank.

2. Connect a DMM between terminal A and terminal D.

3. Verify the secondary fuel level sensor resistance remains within 40-250 ohm and changes smoothly while moving the float arm from stop to

stop.

瀚慖f not within the specified range or changes erratically while moving the float arm from stop to stop, replace the fuel level sensor.

DTC Descriptors

DTC P2714

- Clutch Pressure Control (PC) Solenoid 4 - Stuck Off

DTC P2715

- Clutch Pressure Control (PC) Solenoid 4 - Stuck On

Circuit/System Description

The clutch pressure control (PC) solenoid 4 is part of the control solenoid valve assembly, which has no serviceable parts. The PC solenoid 4

regulates transmission fluid pressure to the 2-6 clutch regulator valve which controls pressure to the 2-6 clutch. The TCM calculates gear ratio

based on the RPM signals from the input speed sensor (ISS) and the output speed sensor (OSS). The TCM compares the expected transmission gear

ratio to the calculated gear ratio for each commanded gear.
