Hello all....
had the usual throttle body ETS symptoms so I replaced the position sensor with the magnet uograde .. 1999 V70 base non turbo 125k miles

Started right up idled fine drove it 3 blocks and ZAPPO

Back to the same Ole rough as a cob running throttle bouncing around etc limped it home

And now what ??

Any ideas appreciated

Thanks
TJ

 

scan, write down the codes,clear the codes, wait for them to reset and scan again. That should give you some insights as to whether its an ETM issue or something else like a vaccuum leak, fuel pressure etc. Did you clean the MAF when you were doing the repair? Not sure if there is a recalibration required on this model so google around for that as well.

 

Does it always run well for a minute right after a cold start? Is that your normal?

 

Thanks

I am going to replace MASS today

Will reply asap

 

Okay, have fun!

 

replaced the Mass AF and NADA same symptoms HOWEVER i did manage to connect my Bosch piece of junk code reader to the OBD port and Viola
to my surprise i found a 0722 code so now i am leaning towards the speed sensor on tranny to be the culprit
cause i started her back up and it idles ok throttle works just after i drive it , she goes WONKY

 

So I replaced the output shaft speed sensor and still no love 💔

It starts up fine idles nice after I erase codes

But as soon as I Rev it up past 4000 rpm or so it goes right Into limp mode and ETS light pops on ??
then idle surges badly

Help
