Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
VRS Sensor (NAVAJO)
Make sure trigger wheel on crank pulley and VRS are not damaged. Ensure VRS is not touching trigger wheel. If no problems are found, disconnect EDIS connector. Crank engine and check for A/C voltage at EDIS harness terminals No. 4 and 5. If A/C voltage is not pulsing greater than 1 volt, check VRS circuits for opens or shorts. If no problems are found, replace VRS sensor. If A/C voltage pulses greater than 1 volt, go to CHECK VBAT OPEN TO COIL (NAVAJO).
