Ikon Oil Temperature Sensor Issue
Summary of the thread
The conversation revolves around a 2005 Ford Ikon experiencing issues with the engine oil temperature sensor warning light and occasional oil pressure light activation. The problem was identified as a potential bad cable or plug, with a suggestion to inspect the wiring harness for corrosion or damage. The solution involved replacing a corroded connection at the sensor harness, which resolved the warning light issues.

Thanks. The flickering is intermittent, more frequent after the engine warms up. Where on the harness did you find the issue? Was it a visual inspection, or did you need a multimeter?

The issue was close to where the harness connects to the sensor itself. Visual inspection revealed a cracked connector, causing intermittent contact. Given the symptoms you're describing, I'd advise against prolonged driving and consider a workshop visit.

It was a corroded connection at the sensor harness. Replacing the connector and sensor cost 95€, but the warning lights are gone. Thanks for pointing me in the right direction!

IKON

I've seen something similar with my Ikon. Those sensors can be a pain. The oil pressure light is a common symptom when the temp sensor goes haywire. Have you checked the wiring harness for any corrosion or damage? That was the culprit in my case. Is the light constant, or does it flicker?
