Toyota Hiace 1TR timing issue

Post by Darren Fraser »

1TR CKP reluctor
1TR CKP reluctor
This vehicle had issues with sometimes starting but running 50deg BTDC and then in one key cycle would be a crank no start with timing at 125degrees retarded without touching anything.

Turns out that the crankshaft reluctor was fitted back to front and although our cam signal matched a known good, out CKP signal was five teeth retarded.

I tried to do a comparison wave forum on Pico but could figure it out so I did an overlay in excel.

This is the overlay of my vehicle against a known good. Can timing was good but we were five teeth retarded on our CKP.

Thank you Darren for posting and what a great catch

I hope you had some vehicle history prior to diagnosis?

This often leads to the area of concerns and validates that question to the customer "has any work been carried out on the vehicle recently?"

Thank you again, take care.....Steve
