How To Fix P00B5 Code - Radiator Coolant Temperature Sensor Intermittent Fix
Troubleshooting a P00B5 code is tricky because it indicates an intermittent problem with your radiator coolant temperature sensor circuit. This video helps you diagnose why your check engine light comes and goes or why your engine runs rough one minute and smooth the next. Since the part often works fine during static testing, I show you how to perform a wiggle test on the wiring harness to find loose connections or breaks that only show up with vibration. We look closely at the connector pins to see if they are bent or not making tight contact with the sensor. I also discuss checking engine ground connections which can cause signal noise. Sometimes the sensor itself fails internally only when hot, so we cover when it is best to just replace it as insurance. This tutorial gives you the practical steps to track down those annoying ghost electrical gremlins in your cooling system.
