After tinkering with my Golfy i noticed this plug unplugged lol can anyone tell me what it is or what should be plugged into it please?
If your car is 1989 and has a Digifant 1.8 PB code engine fitted, it will be the knock sensor connection. Crank sensor is similar but that only came fitted on the later 8v 2.0 AGG engine fitted to the mk3 golfs. It should be connected to the loom though.
Ye Danster mine is 2.0 8v Kreg, so what problems might it be causin while its not plugged in if any or do people do it for a reason??? Thank you all for the advice lads What was your experience today Dubmeup??lol
I think at Kreg your car should have a 2E engine code that does not have a crank sensor. If the engine has been replaced by an AGG or ADY, they have crank sensors but will not connect to the existing loom as there is no loom for it as the earlier 2E engine uses the dizzy for the ignition trigger unlike the AGG and ADY that use the dizzy as a cam phase sensor.
My experience was changing a crank sensor! Yup, a 2E has no crank sensor but that just doen't look right for the knock sensor to me. The route the cable takes is wrong and the connector doesn't look right to sit in the bracket next to the twist connector. If the business end of that cable goes behind the oil filter it's a crank sensor but as mentioned, if it's an ADY or AGG running on 2E (digifant) management, the loom will have no facility for it as the ECU doesn't use a crank sensor signal.
follow the wire back to where it comes from, simples. if it runs to a black plastic roundy thing held to driver side of block with a bolt thru the middle then its a knock sensor. if it runs down to a sensor bolted right at the bottom of the block on passenger side under filter housing and next to gearbox, its a crank sensor. if crank sensor, you dont need it and you have a late 8v block fitted to early car. if its a knock sensor you do need it, find the other end and plug it in
Thank you Jonny iv jus opened me front door to go see if the wire goes to the black plastic roundy thing lol and the heavens have just opened, il av t wait now lol....how annoying[:^(]
Its the other lead, the one you have a white plastic cap on thats loose, what is that one? Also I found a lead and a connector that were also unplugged, from under the air box and the connector goes into the car itself on the left hand side, its a 4 pin but one is seperate on the end, its like 3 and 1 type thing so i plugged it back in and it drained the bat after turning the car over twice any clues as to what the lead is and why it drained me battery??
the white grey plug is the crank sensor wiring sould be 3 wires in there if its not plugged in the car wont run
