Do not attempt this job unless you have the tool to lock the camshaft in position. Because it has a variable valve timing pulley you will not get it right without the tool.
Ignition timing is controlled by the engine management computer and is not adjustable. Valve timing is set at a fixed position when the timing belt is replaced and not adjustable.
Code is for the VVT or variable valve timing. Was the timing belt replaced recently. If so the timing belt is not on correctly. If it just happened it could be the valve it self, wiring to the valve/corrosion on connectors. Check the oil level as low oil could be an issue. If the belt was not changed recently try changing the oil and adding a qt of Rislone to the oil. It is designed to free up sticky lifters and could free up the VVT solenoid. Worth a try.
This model has one belt for the cam drive system, along with an oil-filled pretensioner. Additionally, these models have VVT (Variable Valve Timing) which consists of a PWM (Pulse Width Modulated) valve and associated plumbing to the hydraulic tappets. This system increases or decreases the amount of TDC overlap (cam timing) based on driving conditions resulting in enhanced performance and lowered emissions. The caveat is that one must be diligent about oil changes and usage of the proper weight oil to avoid clogging of the oil feeds to the tappets.
Albert i will be able to help you with this problem send me a mail [email protected] i have a program with all the neccesary diagrammes and directions to follow the correct timing belt replacement procedure. i will reply with the needed diagrams and instructions.
