Common causes for the P0836 trouble code include: Defective 4WD switch Defective 4WD actuator Damaged electrical components (such as wires and connectors) in the system Defective sensors Defective solenoids In rare cases, a damaged transfer case In rare cases, a defective PCM How do you troubleshoot P0836 ? If the scan tool has that capability, and the scan tool can operate the IMRC valves, then the problem is either resolved and a simple code clearing is all that's left or a new PCM would be called for. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground. If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If this can't be accomplished pull the plugs and check the condition.
