Engine light on after fitting new throttle body

[Rowenb]

Fitted a 70mm TB to my VP V6 other day and hooked all the sensors etc etc up and it started fine getting up to 1500rpm before nearly stalling and settling into an average idle with engine light on. The car hesitates when going from a standing start then lunges forward and very jolty when on hwy speeds if you get off the gas then put your foot back on, gives a clunk so could be diff or drive train. I was thinking sensors or something for engine light, has anyone had the same prob fitting TB's?

Check to see if any error codes have set in the ECU.Its easy and only takes a minute or two.---Checking your Computer for Faults (VN - VP)---

+1 tps sensor code 22???

[Rowenb]

The engine warning light goes off after started but when it nearly stalls it comes on. I'll look at changing the sensors over off old TB first as one that came with the bored out TB had a piece broken off but did not stop the plug from clipping in. So the car book has these codes to know what is wrong after you read the flashing sequence?

[db_notso]

try a search in google for code 22 tps fault its in these foroumns (a full list of codes)
tps controls engine signal for amount of throttle AND auto trans signal for LOAD (tps signal does both)
so if a bits missing of the sensor i would try another one
if the CONNECTOR is damaged may need a wreckers one cut off the loom then SOLDER it onto your engine loom in-place of the dodgy one.

as db_notso said, it is most likely the tps sensor. the way your talking about whats happening with your car, i would be 99% sure its tps. swap it over with your old one and it should fix it buddy

Thanks for the replys will get around to changing sensors around one day. Are the V8 and V6 sensors the same coz i don't know the difference, that could have different effects right?

[db_notso]

hmmm tough one i think the v8 sensor is a different reading at full throttle due to different size throttle bore
could be wrong here though (memory work damn it!)

[zskinner]

nah mate, v8's and v6's all the same tps sensor

[db_notso]

true that like i said a bit of a BRAIN SCRACHER!~

i had a feeling that the throttles had a different MAXIMUM openeing but there you go i guess!~

will keep that in mind next time testing a tps (ill just swap v6 to v8 as i have worksshop spare!~)

Pulled out new TB and replaced the sensors on it with the ones that were on the TB that was pulled off and it went back to working like it did before with no problems and no engine light on. No great gain in power but the car does run well, high flow cat is on the cards soon but i'd reccomend to any one who's chasing power to spend the money and go cam n heads etc n not spend good money on bits that just bolt on. But then again if i do the heads and cam all the crap i've got will pay off. Thanks for the replys.

[db_notso]

good to hear man!~
sometimes you got to go back to basics huh?
change something and it doesnt work chang it back !~
