![]() ![]() I used a small straight pick tool (you could use a thin, strong steel wire or 2~3mm drill bit) and cleared it out by working it through the crud in the stub. This allows air to by-pass the butterfly when on idle and it gets blocked easily as condensation builds up in the hose and dries / hardens, causing the blockage. When you take the throttle body off, you'll have a small bore rubber hose going from the rocker cover to the lower right hand side of the body onto a small brass stub. Take the throttle body off, get some carb cleaner (or use petrol and a cloth) and clean the carbonised gunk from the body above and below the butterfly flap.Īlso a common problem is the idle air by-pass port gets blocked up (like this one was). Just fixed my wifes 2002 1.8LS Vectra with this fault. Just as I was about to paste this in from Word saw that Andrew Moorey had replied and he?s the man to advise on a technical basis.Ģ002 1.8 - Engine Management Light - The-Mechanic ![]() However I don?t know if it?s a MOT failure? ![]() The car had lost power and was in limp home mode so had to be done but cost was £950.00.Īfter that bitter experience if the management light came on again (please don?t) and the car was running OK I would leave it until a permanent fault develops. That was not the case and they replaced mine and eventually took it to a sister main dealer who found it was the CAT which had collapsed. Main dealer had it for a week and they said it was the turbo and fitted a new one. My mates Vauxhall tech 2 reader suggested a MAF sensor but he said they often get false readings at work with these and they simply replace components until it works. My small local garage?s reader suggested a wastegate solenoid but he was reluctant to change it due to the expense and with no guarantee of success. ![]() The management light on my Vectra came on and ran in limp home mode. He also said that if it does come on again (which it has) in the meantime, it could be the Throttle Position Sensor malfunctioning and if it is the whole unit will have to be replaced, costing around £300! Apparently I can't just replace the sensor, I have to replace the whole throttle body!Īs I said earlier, when the Management light is on, the car seems to run OK with no ill affects.Ġ2 Vectra Engine Management Light - wemyss Now he said it could just be a blip, and that I may never get it again, so he cleared the memory for me. I took it to a local garage with the right equipment to read the fault code for me and he said it came back with the code p1555 TPS Sensor. It has no affect in performance when it is on. The engine management light has been coming on intermittantely on my 02 plate 1.8 Vectra for around the last 3 to 4 months. I was wondering if someone could help me with a query. 2002 1.8 - Engine Management Light - GazKaz ![]()
