Check VRS Resistance

Turn key off and disconnect PCM. Connect negative lead of ICM diagnostic cable to negative battery terminal. Set DVOM to 20-k/ohm scale. Measure resistance between breakout box pins No. J48 (VRS

If resistance is 2580-2700 ohms, go to VRS SENSOR. If resistance is not 2580-2700 ohms, repair wires between VRS and ICM or replace VRS.
