Adamw Posted July 14, 2017 Report Share Posted July 14, 2017 I've setup the trigger values as indicated by the online help for subaru quad avcs and checked those many times but I'll give it another look. I'll try and search the forum again to try and find the other person who is having this problem that you are helping with, sorry you are having to do things twice for two different people. Dont just go off the offset values quote in help as all engines vary a bit. There is a "Cam Angle Test" function in the software to determine the correct values for your engine. Use a test pulse count of 3 for the intake cams and 2 for the exhaust cams test. The procedure is well explained in the help file. The other user I was working with is via our tech support system. I cant remember all the details but it feels similar. Update:Today I ran a completely new set of wires to the RH Intake AVCS Cam Sensor all the way from the sensor to the ecu...still no dice though. Is it possible that if the timing were off a tooth or so I would get a "no signal" error on the ecu? I would think it would still be seeing a signal if this were the case. I swapped the sensor for a known good one so that should rule that out. This is most puzzling. Thanks for the help.The "no signal" error means exactly that - the ECU is not seeing any signal. If it is seeing the signal but the wrong timing or number of teeth etc, then you will get the "cannot sync" error.I dont know these engines well, but take a look at the picture linked in this post: http://forums.linkecu.com/index.php?/topic/4931-wiring-camshaft-angle-sensor-subaru-ej25/&do=findComment&comment=29659 Its pretty odd this picture shows a different pinout on the LH vs RH sensor. Do you know anyone with an oscilloscope? Where abouts are you in the world? Quote Link to comment Share on other sites More sharing options...
