pugpete1108 62 1 Cars Posted September 29, 2006 right just started stripping down the 6 lump and need to know what sensors on the block are what. i have got a couple right i think, but can anyone give me definite answer? 1. cam position sensor? 2. water temp sender/sensor (not sure which) 3 as above? 4. oils something??? 5,ditto 6.ditto 7.ditto 8.oil level indicator Share this post Link to post Share on other sites
sonofsam 5 Posted September 29, 2006 7)Oil pressure. 8)Oil Temp?, well , you use the dipstick for level:P 5) Knock sensor. Share this post Link to post Share on other sites

welshpug 1,627 Posted September 29, 2006 from the haynes book of lies - "the oil level sensor is located on the block just to the right of the oil filter", so I guess this would be 5 oil temp is in the sump so thas no8 oil pressure is above the oil filter so thats no7 Knock sensor is screwed into the front face of the block, there should be a botl securing the sensor to the block rather than being a screw in unit. if it had aircon it'll have the cooling fan switch on the thermostat housing as well as the gauge/temp warning light Share this post Link to post Share on other sites
jonnie205 1 Posted September 29, 2006 7 is actauuly an oil prssure warning light not a gauge. If you want to run an oil prressure gauge you will ahve to remove that light switch and make an adaptor to run the 8v pressure sender. I have been told s16 one will fit straight in but i have never tried myself. Only phase 1 gti6's had oil pressure gauge Share this post Link to post Share on other sites
pugpete1108 62 1 Cars Posted September 29, 2006 (edited) right then we are nearly there 1. cam position sensor? 2. water temp sender ( guage/warning lamp) 3 water temp sender ( ecu) 4. ????? 5,oil level sensor 6.knock sensor 7.oil pressure 8.oil temp sender and yes just looked and there is a hole for where the extra sensor should be for the air con , but i won't be needing that will i? i can just block it off i wonder what number 4 is then by the way what haynes was that in? i didn't think they made one for the gti6 Edited September 29, 2006 by pugpete1108 Share this post Link to post Share on other sites
welshpug 1,627 Posted September 29, 2006 (edited) ah, I'm being clever the xsi is identical bar the cam sensor I believe lateral thinking, thinking sideways like the Citroen AX haynes manual never had much on the 1.5 D engine, but I had a 1.5 D powered AX, so I bought a pug 106 manual as the late P1 and P2 all had the 1.5 version Edited September 29, 2006 by welshpug Share this post Link to post Share on other sites

sonofsam 5 Posted September 30, 2006 Is no. 4 a tapped hole? my engine has the feed for the turbo there.just checked Share this post Link to post Share on other sites

pj838 0 Posted March 9, 2007 Got some stuff on my 6 engine (phase 2 with PAS and Aircon) I need to know what it is, any help appreciated! Thats the loom obviously This is the plug inside a heat-wrap... what is it please? This is part of the inlet manifold/throttle body...? This is the main/fuel relay, but what is the plug>>? This blue plug I don't think was connected when I picked the engine up, and I think its been snapped..? Thanks Share this post Link to post Share on other sites
smighall 1 Posted March 9, 2007 2nd pic: Vehicle Speed Sensor to drive an electronic speedo. Plugs onto the speedo housing on the gti6 gearbox 3rd pic: Stepper motor, or idle control valve. Bolts on the inlet manifold underneath 4th pic: Dual Relay, and fuel cutoff switch plug. You should have a plug with a red rubber cap that fits in. If not just bridge the 2 wires to bypass is. 5th pic: I think that's for the PAS to raise the revs at idle if need be? Share this post Link to post Share on other sites
pj838 0 Posted March 12, 2007 Thanks a lot for that smighall So I will just leave that 6 speedo connector unconnected when I wire the loom into my 205. The fuel cut off plug I will prob do like you say and solder the 2 wires together. The PAS plug I will just leave as my car will not running PAS or aircon. As I understand it so far, I won't need to do anything to the smaller of the 2 multiplugs, just split the other bigger one and wire it up... getting a 306 haynes next week. what could possibly go wrong Ah one more unidentified connector I have: the arrowed one is a brown 3pin plug- ?

Malachy 0 Posted March 12, 2007 ]the arrowed one is a brown 3pin plug- ? looks like the crank sensor to me. Share this post Link to post Share on other sites
smighall 1 Posted March 12, 2007 Yup looks like the crank sensor to me too. The sensor that bolts in the top of the gearbox Share this post Link to post Share on other sites
littlemike 0 Posted March 12, 2007 (edited) The broken blue plug's probably off the oil temp sensor on the sump. They're prone to getting damaged if you've got the engine sat on the floor. Regarding the speed sensor the ecu uses it to calculate what gear you're in and to slightly hold the revs up when rolling to junctions, probably more too?! There are sensores around that have the 3 pin connection for the gti6 loom and also have a pass through for the 205 speedo cable. They're hard to find though, but without one your ecu will store a fault although it's not serious enough for it to bring the fault light on. The 306's carbon canister valve needs a resistor fitting in it's place too or that will do the same. Edited March 12, 2007 by littlemike Share this post Link to post Share on other sites
pj838 0 Posted March 14, 2007 Thanks for the info guys. I have the plug which connects the sump oil temp, its a different one although you're right its a bit the worse for wear. Will it be ok to leave the crank speed sensor unplugged (for now at least), will the engine run ok without it? Ditto the canister valve? I know it sounds like I want to leave a lot of stuff out but I want to find out the minimum it takes to get it running and then sort out the minor problems. I got this diagram from the 306 forum one of their articles, it looks quite useful: or is it ? Share this post Link to post Share on other sites
fletch 0 Posted March 14, 2007 I don't think the engine will start without the crank sensor, as the ECU can't tell how fast the crank is spinning. Share this post Link to post Share on other sites
Malachy 0 Posted March 14, 2007 I don't think the engine will start without the crank sensor, as the ECU can't tell how fast the crank is spinning. you can't leave the crank sensor out this basically tells the ecu how fast the engine is spinning and what position it is in (its reads your flywheel teeth 60-2 wheel) thus enabling it to time injection and spark. if the ecu does not see any rpm it will not spark and it will not inject fuel!

The 306's carbon canister valve needs a resistor fitting in it's place too or that will do the same. I have one of the sensors knocking about I set up a 306 s16 conversion without the carbon canister, no resistor etc and its never had any issues. I left it plugged into a solenoid that basically done nothing Share this post Link to post Share on other sites
Matt Holley 11 Posted March 15, 2007 1. cam position sensor? 2. water temp sender ( guage/warning lamp) 3 water temp sender ( ecu) 4. ????? 5,oil level sensor 6.knock sensor 7.oil pressure 8.oil temp sender Just to through a spanner in the works I recently removed the loom from a xsare vts engine and it didnt have a plug on number 7 and didnt look like there ever was , I also noticed this on dixons engine when we were doing his conversion, how ever there was a plug on number 4 so I think that is what is used for the oil pressure light. Anybody else had this? I will have to check with one wired into the car but if there is a spare hole for an oil pressure sender then that can be used for a gauge Share this post Link to post Share on other sites
