Signal Too High






Signal too high

Checking the gas level sensor signal




- Ignition on.
Read off the gas level.
Check to see if the fault is permanent or intermittent by reading off the gas level (derived from the gas level sensor signal) in the fuel tank.
If the read off volume exceeds 4 liters (approximately 0.88 UK gallons) the gas level sensor is functioning. The fault has previously existed but is now intermittent.
If the read off volume is 4 liters (approximately 0.88 UK gallons) and the gas tank is not empty, then the fault is permanent.

Note! If the gas tank is empty even though a volume of 4 liters (approximately 0.88 UK gallons) is then shown which makes it difficult to determine whether the fault is permanent or not.









Continue - Checking components and wiring

-------------------------------------------------

Checking components and wiring

Hint: If diagnostic trouble code (DTC) DIM-02 Fuel level sensor is stored at the same time, then there is a fault in the common ground lead for combined instrument panel terminal #B17.

Check the gas level sensor and combined instrument panel connectors. Check for contact resistance and oxidation.
Check the resistance of the gas level sensor between terminals #1 and #2 on the sensor by the gas tank. The resistance must be between 79 ohm (full tank) - 1104 ohm (approximately 5 liters remaining).
Check the signal cable between combined instrument panel terminal #B8 (#8) and gas level sensor terminal #1. Check for an open-circuit. Check for a short-circuit to supply voltage. Also check the cable between the sensor and the connectors.
Check the ground lead between combined instrument panel terminal #B17 (#17) and gas level sensor terminal #2. Check for an open-circuit.
Remedy as necessary.

Verification




Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Read off the gas level in the fuel tank.
If the read off volume exceeds 4 liters (approximately 0.88 UK gallons), the gas level sensor is functioning.
If the read off volume is 4 liters (approximately 0.88 UK gallons) and the gas tank is not empty, then the fault remains.

Note! If the gas tank is empty, a volume of 4 liters (approximately 0.88 UK gallons) is then shown. This makes it difficult to determine whether the fault is still present or not.









Is the value OK?

Yes - VERIFIED

No - VERIFICATION FAILED

Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test
