SamGTi 0 Posted February 12, 2008 I don't post much in this section as I have an XU engined 205 but a mate of mine has just bought a 1999 Saxo VTR. On his first drive today, it ran fine for about 10mins until it simply cut out mid-drive and wouldn't start for about 20mins. It turned over fine, all the electrics worked, but it just wouldn't fire up. Then when it eventually did fire up again 20mins later it got us home again no problems (only 2mins mind). So does anybody know why this might have happened? Share this post Link to post Share on other sites
welshpug 1,657 Posted February 12, 2008 TDC sensor I'd say, quite a common occurance on the TU it seems. Share this post Link to post Share on other sites
SamGTi 0 Posted February 12, 2008 Sorry, but what is the TDC sensor? Share this post Link to post Share on other sites
welshpug 1,657 Posted February 12, 2008 TopDeadCentre sensor, or crank sensor. without a signal from this you get no spark or injector pulse from the ecu. there are 2 types as far as I can tell, VIN will confirm. 1920Z3 SPEED SENSOR 31.66 GBP 37.20 GBP 19205T SPEED SENSOR 15.87 GBP 18.65 GBP Share this post Link to post Share on other sites
SamGTi 0 Posted February 12, 2008 That's great, thanks welshpug. One more question, is it hard to change this sensor? Share this post Link to post Share on other sites
joe1joe 3 Posted February 12, 2008 one bolt and a plug 2min job! Share this post Link to post Share on other sites
welshpug 1,657 Posted February 12, 2008 nope, single bolt and connector. It may be obstructed by the intake pipework and possible the air filter, its been some time since I had a poke around in a TU engine bay. I'm not saying its 100% that, but it is very common and does cause the symptoms described, not many other parts can cause this, the only way to be 100% is to get it on a diagnostic machine while the fault occurs.
