Throttle Position Sensor - TPS - M13A

I am trying to get hold of a new TPS for my Jimny as it is at fault.

Having checked the output on a diagnostics reader it is very erratic and the stored fault code confirms it is at fault.

Is this sensor a main stealer only part? Euro Car Parts don't have it and I can't find one on the web or eBay... I bought a used one from Cam Suzuki but the housing was broken stoping the connector staying attached so that has gone back and unfortunatley they have no more.

I know it's made by Mikuni but does anybody know the part number or where I can get one?

Was the same one used on any other models with the M13a motor?

FYI, this was causing my Jimny to stall when braking at junctions. With it unplugged the Jimny runs OK on the map sensor alone. With it connected you can hear the injectors ticking as they are being rapidly switched due to the TPS's unstable output.

TIA

test it using this it might help it may be a wiring fault not the sensor

Second hand or main dealer part only I would have thought mate.

Thanks for the replies and info all!

Wiring is OK so it must be the sensor...

Martin, is the genuine Suzuki one much more than that from Spectromatic?

Anyone else fitted a non standard one / copy?

if you check the out put like i posted up and you get the same sort of result then i say the sensor is ok

No eBay APP ID and/or Cert ID defined in Kunena configurationQuick update lads.

After checking the output as per the info above I verified the sensor was definitley at fault.

When the clowns at Suzuki told me they wanted £198! for one I decided to take a punt on this from eBay USA for £38 delivered!



It arrived in 10 days and looks to be a genuine Mikuni part. Not boxed but looks and is marked up just like the old one I removed.

Fitted fine and after resetting error codes all appears to be good.

Looking at the graphical output it correlates exactly with throttle position and does not spike all over the place like the failed one did.

However... All is not rosy! I now have a primary lambda sensor error for the heating element.

This maybe a coincidence and totally unrelated or could be caused by me driving with the TPS disconnected for 4 weeks which may have lead it to run rich as it was definitley using more fuel than normal.

The actual O2 sensor is still giving a reading so its not totally knackered but will be replaced.
