AFM sensor switching

[MarylandMr2]

My 93 mr2 3sgte AFM sensor just took a shit, so i went to the dealer to get a replacement...$650. screw that, so i found a cheaper($250) remanufactured 92 3sgte on the internet. i was wondering if this would be compatible? same engine, should work right?

you can call toyota and ask them...... obd systems were changing rapidly in the early 90's, so there's a chance they're different

sure aslong as the harness connects...

all Air flow meters work the same way... there is only 3 different kinds between every manufacturer and they for the most part operate the same way...

MR2 uses the Vane type... i wouldn't even imagine the harness connector would be different. toyota is great that way.

but don't send me a bill if it doesn't

isn't there a way to bypass the AFM?? Like Jeff Fazio.... I think he mentioned that B4

yes, but you will have to find a different way to measure and balance A/F ratio... eg.-EMS

Try rockauto for this part..

or a re-flash in the stock ECU that will remove MAF parameters... but then you would need a way to sense load... i don't think the 3SGTE has a MAP sensor. so yea... um... your right

The only way to get rid of the AFM is an HKS VPC or an EMS.
I would not recommend the HKS VPC.

There is no reason that you should not be able to use the 92 AFM on the 93 MR2, AFAIK.

only if you remove it completely...
