Component Inspection

WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.

Ignition switch is turned "OFF" without engine running.
Disconnect hose connecting FTPS to the Fuel Tank.
Using a vacuum pump, apply vacuum to the hose connecting to FTPS.

Measure FTPS output voltage between signal terminal of the FTPS harness connector and chassis ground.

Specification: Voltage increases proportionally with decreasing pressure

Pressure (kPa)	Output Voltage (V)
6.666	4.5
0	2.5
-6.666	0.5

Is voltage within the specification?
YES
- Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known-good FTPS and check for proper operation. If the problem is corrected, replace FTPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
