Hi im kevin have you had any water ingress into car ?
Ok in that case you have two choices either water has entered ecu box and damaged relay wiring or relay or the relay has failed heres where to check and the relay youll need to change
Replace this relay it will almost certainly be the cause it controls engine power and camshaft adjuster power inputs
Can you test pin 121 on engine ecu it should have battery voltage with ignition on
Unplug multiplug from ecu and check pin on plug
Can you check to see with ecu plugged in if on the main relay pin 4 switches to earth with ignition on ?
The relay i told you to change this is the one we are testing from
Yes you need to see if its grounder put meter on volts put positive lead on battery positive and negative lead on pin 4 and it will show 12 volts if grounded
Do you have continuity between fuse 29 inside car and pin 6 on relay
Have you checked fuse 29 ?
Im gonna opt out im in the uk and its late let see if another techs got any ideas

I am confident we can resolve your problem together. Pleaseunderstand that I don't know your skill level.

We didn’t build these complicated vehicles; wejust diagnose and fix them.

I am also going todirect you with the fastest, easiest and most common things to check first. Please bepatient and permit me to do what I do best.I also try to give all of the information you may need, expecting a “positive rating” inreturn. I will also continue assisting you after you have rated me, if necessary. If thereis any reason I cannot get a positive rating, please let me know why “in advance”, so Ican go another direction for you.

If you do not understand it, or you need more information from me, or need me to go in more detail
I do need a vin # ***** the vehicle please to get the factory wiring diagram to assist!!
please look at pic you need to check the resistance of the wire highlighted from ecu to the relay connector pin .
please let me know what is the resistance
too high must be less than 1 ohm . run a another wire in paraell from 62 to 9 and see if the code goes away after clearing and starting the vehicle
thanks for letting me know this !!
with 8 teeth sheared off of the belt there is a great chance that the valves are bent . very expensive repair.
the cylinder head needs to be removed and new valves and valve job is needed.
need compression first before anything else!!!
yes my pleasure!!
