      I changed timing belt due to jumping 2 teeth, replaced all exhaust valves due to front head valves bent, replaced water pump, adjusted all valves. Now I have a po389 crank sensor code, VTM-4 light on, VSA system indicator light on, VSA activation light on. Never had any lights on prior to repair. Took crank sensor off and cleaned with carb cleaner incase coolant had gotten inside the connector. Checked all timing marks like 5 plus times and everything is spot on the marks. I tried unplugging battery overnight and doing idle relearn procedure and no difference with the lights. so any advice for this issue would make this mechanics hair stop falling out.

        Please do not click on the above two links, I got a warning from my antivirus that it leads to a known website for malicious activity.


          You said you did an idle relearn. But what about a crank\cam relearn?
