| SUBJECT: | DTC B1500 and Fuel Level Sensor Replacement Procedures |
INTRODUCTION
This Service Information bulletin serves as a reminder to always follow the proper procedures when diagnosis of a DTC B1500 leads to replacement of a faulty main and / or sub fuel level sensor.
SERVICE PROCEDURE / INFORMATION
When DTC B1500 is found in memory, always start by following the diagnostic procedure in the applicable Service Manual. If diagnosis determines the fuel level sensor(s) (main and / or sub-level sensor) is faulty, always reference the applicable Service Manual when using the steps below:
- If the fuel level is above 2/3 full, drain the tank so the remaining fuel level is below 2/3 full. The recommended method for draining the fuel is by using the vehicle’s fuel pump. Follow the “Draining Fuel with Select Monitor” procedure in the applicable Service Manual.
IMPORTANT: Always confirm the container the excess fuel is being pumped into is clean.
- Once the fuel level is below 2/3 full, remove the faulty fuel level sensor(s) following the procedure in the applicable Service Manual.
- After removing the sensor(s), inspect the inside of the fuel tank for any foreign material or debris and remove / clean as necessary.
- Install the replacement fuel level sensor(s) in reverse order of removal.
- Refill the tank with the drained fuel (where applicable). Use a filtered funnel whenever possible.
NOTE: If fuel was drained without using the vehicle’s fuel pump, it should not be reused due to risk of contamination.
- Clear the ECM memory, confirm the DTC does not reset and verify proper operation of the fuel gauge before releasing the vehicle.
IMPORTANT REMINDERS:
- SOA strongly discourages the printing and/or local storage of service information as previously released information and electronic publications may be updated at any time.
- Always check for any open recalls or campaigns anytime a vehicle is in for servicing.
- Always refer to STIS for the latest service information before performing any repairs.
