for reference, these are the pin references I eluded to earlier in the thread - I tested the earth at the THA connector back to pin E2 on the above map - single brown wire on the 26 pin plug - and got no continuity, again making me believe it's the earth for that sensor. I will be double-checking the rest of the sensor loom now too after reading your reply

thanks a bunch for your reply mate, there's a lot of good info in there for me to work off. It's still got the standard ecu and it seems better now than before but it had a blip earlier, that may however be because I've earthed it back to the chassis so it's not filtering the noise correctly like you previously mentioned so I'll take a look at that too. I'll update this with my findings

I've snipped the earth and connected the sensor earth to ground at the point where the gearbox is earthed in the engine bay. I'm really unsure as to whether this has solved the problem as it still smells rich but doesn't sound as aggressive. can anyone suggest if this should sort this issue or if there's something I'm missing here? going to leave it as is for today and see if the fuel is still being guzzled or not

okay I've sussed it now to be a break in the ground wiring for the sensor as the ECU common ground shows continuity to the battery but the brown with white stripe wire (sensor earth) has an open circuit between it and earth. I checked a really good wiring diagram found on this forum and it looks like there's a common intake earthing point, does anyone know where it is located? the wire goes through the bulkhead and I don't have time now to strip out the glovebox and dash. thanks in advance

Hi guys I'm an ex-mechanic looking for a bit of help with my girlfriend and mines new purchase. '98 Starlet GLS, 4E-FE N/A So the car runs fine except that it's haemorrhaging fuel like there's a hole in the tank (checked, it's not that lol). the dude who owned it before us stuck a K&N cone filter on it and in his infinite wisdom tagged up the plugged in Air Temp Sensor (THA) to the back of the engine bay in a plastic bag. after noticed the oil rebreather was pretty clean I replaced the pipe with the old sensor grommet and fitted it to the filter. this sorted out the fuelin
