Hello,

MS2pnp TPS calibration on a '91 mx5

My TPS calibration does not work. without clicking "get current" on high and low
the values are 0 and 1023.

When I push the "get current" button low and high become both 0

Sensor is wired up correctly, measured out with an ohm meter, works fine.
Also the 5V and ground are ok.

what am I doing wrong?

thanks

 

your 91 doesn't have a vtps.

 

I've removed the original one and installed a VTPS.

this one:http://www.efi-parts.co.uk/index.php?productID=190

Why no signal?

 

Brain?

 

dunnoz.

 

Anybody else to give it a try please?

Added my .msq file if it helps?

 

did you push the gas pedal down when you hit 'get current'?

 

I'm a noob but not that stupid

Yes, I did.

 

Do you have the VTPS jumper enabled? It's a pull off jumper on the lower board.

 

Thanks Matt,


problem solved!

Found nothing about a VTPS jumper in the manuals... But it's there


thanks again!

 

It's mentioned towards the end of the '90-'93 install guide as this is specific to these cars.
