Deep 30mm socket, and an appropriate extension (preferably the wobble drive type) ;)

Haha i hear that! Just wating on the ramps now - thanks for the help guys. At least when this happens to another newb they will have a FAQ to look at 8) BTW, the second hand sensor cost me $75 from Hillside auto wreckers in Upper Hutt. They still have another one if anyone else needs one.

An MR2 knock sensor is much easier to get to than a GT4 one! Heres a pic anyway, got mine on ramps at the moment :)

Its the sensor smack bang in the middle.

Right, all sorted. I got the new knock sensor in withouit a hassle. The old one was starting to corrode, so it's a good thing I got it out before it fused itself to the block :P
The error codes are still comming up (34 and 52), even after I reset the ecu and disconnected the negative terminal. Its boosting normally and running sweet as though :) What else can I do to get rid of the stored error codes?

Try pulling the EFI fuse i think it is. Pulling it resets it afaik.

And leave it out, or disconnect the battery, for at least 30 seconds

Sweet as - that did the trick :) The weird thing is the speedo read exactly, and I mean exactly, 155,000k when I replaced the sensor. The car must have known something :lol:
