many thanks rich

Other than eBay (or a Toyota dealership) I can't think of a source. If you could get hold of the precise part number you would then know which other vehicles use the same sensor or its equivalent. It's not as if they make different Lambda sensors for every car - there's only a very few models around!

You will get a universal one on Ebay for approx £40. It will come without a connector on the wires so the old one will need cutting off and the wires crimping together. Just do a search for previa lambda sensor.

NEVER use universal Lambda sensors on Jap cars, they operate at a few millivolts different to European produced cars, it'll run, but will probably be worse than the failing one you have.

Indeed, the universal ones are so hit or miss that we don't even fit them to Euro cars, we will only replace like for like, either the dealer parts, or fitting an NTK one in place of an NTK, or a Bksch in place of a Bosch or a Denso in place of a Denso. You get the drift.

Anither problem is that the universal ones require you to graft the wires onto the OE plug, but doing this can crimp the refernce oxygen supply to the fresh air side of the sensor, rendering it unable to sample fresh air and having nothing to campare the exhaust gasses with.

In short, if someone mentions universal sensor..........run away.
