Test Procedure
- Turn ignition off. Disconnect FLS 6-pin harness connector. See Fig 1
. Turn ignition on. Measure voltage between ground and FLS signal circuit at FLS connector terminal No. 1 (White/Green wire). Voltage should be approximately 5 volts. If voltage is as specified, go to next step. If voltage is not as specified, repair open or short circuit between FLS connector and ECM connector as necessary and go to step 3
.
- Turn ignition off. Thoroughly check FLS sensor for loose, bent, corroded, contaminated, deteriorated or damaged connector terminals. If connector terminals are okay, temporarily install a known good FLS and check for proper operation. If problem is corrected, replace FLS and go to next step. If connector terminals are faulty, repair or replace as necessary and go to next step.
- After repair, return vehicle to original condition. Clear codes using Hi-Scan Pro/Kia Data Pro Scan tool or equivalent. Verify repairs by driving vehicle and monitoring for pending codes. If DTC is set during test drive, follow appropriate DTC test procedure.
