In my S13 - I fitted a completely stock S14 SR20DE(VVT) bar the exhaust manifold and exhaust, the rest of the engine is completely stock, but for an NA - it seems pretty horrendous on fuel... Like it'll probably do 40 miles to a tenner if im lucky, and that's driving steady! Im running a 6 speed S15 Box and a 3:9 diff - so not horrendously short gearing either! I've had a snoop around the engine bay and cant find any obvious fuel leaks, I've yet to check under the car but just wondering if theres anything else I can check once I've ruled out the above... Ta, Charlie
How can I test these? Never had much dealings with this sort of stuff before unfortunately... Just seen prices and its looking like £20 for a new Temp Sensor which is fine, but as above, how can I test them to make sure the wiring is even working? Butchered loom as its an S14 SR20DE into an S13
oh right, no fucking idea then I'm afraid. I know the S13 has a separate mini-manual for some electrical bits on the engine, including testing procedures for them (You used a multi-meter on the sensors I think) Not sure if the same is true for the non-turbo SR engine though, you'll have to spend some time going through workshop manuals to see what the diagnostic procedure is on those sensors. Problem is the sensors could be totally fine and the issue could be with dodgy wiring, all it takes is one crossed-wire or one bad earth and it all go's to shit.
Ye that's my concern! I've ordered a new thermostat and temp sensor anyway, only £30 delivered so get them fitted this weekend and see whats what
On idle, the signal wire from the lambda should jump between 0-1v constantly to indicate the fueling is correct, and also when your driving at a constant speed. If it hangs at 1v or 0v constantly, something is wrong with fueling (I think 1v is rich, but each manufacturer is different). It doesnt mean lambda is faulty, although could be.
Replaced coolant temp sensor last night did a 53.4 Mile journey today, mixed between motorway and town stop/start driving - brimmed the tank before hand, then brimmed it when I got back(same petrol station each time) used 6.08L of Petrol which is 1.337gallons 53.4 Miles divided by 1.337gallons = 39.9mpg If my calculations are correct? This wasn't driving like miss daisy either
Nah, the resistance will still change as the temp does. Just put the multimeter on the pins. Can't remember what the resistance values should be, but it's in the FSM somewhere
no way!! Sure that's mapped correctly? that's ridiculous! Just did Driftland in Scotland, and its 260ish miles each way, cost me £35 in fuel each way, and then £35 of fuel for drifting all day Thursday
