DISTRIBUTION SYSTEMS ­ FAULT CODES<br />

14051­FUEL TANK LEVEL SENDER OPEN CIRCUIT OR SHORT TO<br />

HIGH VOLTAGE<br />

NOTE: When the cause of the error code has been rectified, clear the error code and test the system for normal<br />

operation.<br />

Cause:<br />

Possible failure modes:<br />

1. Faulty connector<br />

2. Faulty fuel tank level sender<br />

3. Faulty harness<br />

4. Faulty instrument cluster<br />

Solution:<br />

1. Check the fuel tank level sender potentiometer in H9 channel 25.<br />

A. Remove the fuel tank sender. With the connector still connected move sender from the maximum to minimum<br />

position. If the values do not change continuously between 50 and 400 steps continue to step 2<br />

B. If values displayed are okay, while in H9 channel 25 wiggle the harness and connectors to check for a<br />

intermittent circuit. Channel 25 values will change if an intermittent circuit is detected, repair or replace as<br />

required.<br />

2. Check the fuel tank level sender connector C022, the instrument cluster connector C081 and the inline harness<br />

connector C020.<br />

A. Ensure the connectors are connected, not damaged, the pins are in the correct position and that the fit is<br />

tight. <strong>Repair</strong> or replace as required.<br />

B. If the connectors are okay, continue to step 3<br />

3. Check the fuel tank level sender operation.<br />

A. Disconnect connector C022. Check between the component side of the connector C022 pin 1 and 2. If<br />

the resistance indicated is not between 30 Ohms at full and 250 Ohms at empty, remove and replace the<br />

sender.<br />

B. If the resistance indicated is okay, continue to step 4<br />

4. Check for an open circuit.<br />

A. Disconnect connector C081. Check between connector:<br />

C022 pin 2 (G) and ground<br />

C022 pin 1 (G) and C081 pin 14 (G)<br />

If an open circuit is indicated, repair or replace the harness as required.<br />

B. If an open circuit is not indicated, continue to step 5<br />

5. Check for a short to + Ve voltage.<br />

A. Turn the key start ON. Check between C022 pin 1 (G) and ground. If a short to +Ve voltage is indicated,<br />

repair or replace the harness as required.<br />

B. If the harness is okay, download the correct level of software. If the fault re­occurs, remove and replace<br />

the instrument cluster.<br />
