Hi there dastartly.

I too have been having problems with my tps here in Iceland but in a way it is way to rich and the engine runs very funny and the exhaust sound is some how deeper.(my zx12r has about 23k miles) I have just unplugged my tps (the upper one) on my B5 and then it runs ok but the red FI light comes on, but it runs better(not so terrible rich, it burned almost 2x of fuel) It to hesitates at 5k rpm but runs fine after that. I have not gone to the measures to measure my tps but it is faulty for sure. So I think the next step is to find one on line or at the next reasonable us dealer. 150 us buks is not too bad if it fixes the problem.

Do you have a manual for your bike it's not a big job to check it out and che I the Ecu aswell it could be another problem not the tps it could be an earth problem or power supply
When you use your manual it tells you what to do and where to do it my manual is for earlier mods sorry but good luck I hate electrickery problems Craig

Hi guys noobie on here and looking for some help. My 2000 a1 zx12 has developed a really horrible coughing/ spluttering/bucking between 3500-4000 revs it's rite at motorway speeds. [email protected]#[email protected]@in nitemare to ride. At first I thought it was dodgy fuel. I have had the injectors and rail cleaned, new fuel pump fitted and I disconnected pc5 just to eliminate it. It is even worse now. Could it be the tps? I have no idea how to test it or where I can get another.
Cheers guys

Hi yes when the bike started this I had plugs oil and filter done. It was about due so I thot I would start there. No change. Then put some fuel system cleaner in the tank for the next 4 or 5 fill ups. No difference. Disconnected pc 5. No change. Got the injectors and rail back during the week. The guy said there wasn't enuf gunge in them to cos the problem. Fitted them at weekend. Even worse???

As this is a common problem here is some information.
The zx-12r A to B2 use the same TPS (throttle position sensor) where as the ZX-12R B3 onwards use different ones and the plugs are smaller so you can't use the patch in test lead.

While I have found the patch in plugs to make up test leads for the zx-12r A to B2, (hopefully I'll make 5 patch in test leads this week) Kawasaki part number 57001-1521 Though the one I bought look like a bodge job.
I've not found the smaller plugs yet to make test leads for the B3 onwards.

How to set one up can be found here. The Kawasaki ZX-12R under modifications

im pretty sure the TPS from an early Yamaha R1 also fit, I think the 1998 R1 was a direct swap for my 2002 12, I just happen to have a spare from my R1 lying around when i needed one not that this helps Craig

if anything goes wrong check the battery
no longer a rider but still an enthusiast

Ninjayorkie thanx for that info. You have given me more info in one message that the kawasaki dealer I emailed. I'll get a new one and hopefully thatl cure it. Is there any particular way to set it up once I have put new tps on?

You've got a PC5, you can set the TPS voltage when plugged into the laptop

How to set one up can be found here. The Kawasaki ZX-12R under modifications on DRP's zx12 site.

Built my first TPS test lead last night, 3 or 4 more to do. Minimum order of plugs was 5 sets, so seems a waste not to make 5 sets. Built the rest today. But what to do with them.
1 has already gone to DRP, so if you live near him, ask him, to set or check your TPS for you.
Also built 5 for the B3 onwards.

ZX-12R A to B2. 1 test lead left, and the one I bought of Kawasaki.
ZX-12R B3 onwards. 2 test leads left.

I built these with bullet sockets so the multimeter probes can be stuck between the bullet connector and its plastic boot, this tends to hold the multimeter probes in place so allowing hands-free for TPS adjustment.



ZX-12R B3 Onwards TPS Test Lead, smaller plugs.


ZX-12R B3 onwards testing.
This is on my B4, your readings will be different due to settings or meter used. My readings are just on the low side, and I might nudge them up, I'm undecided.
The engine does not need to be running at any time.



Resistance Checks, patch cable fitted but loom left disconnected. When opening the throttle check the resistance rises smoothly.




Voltage checks, patch cable fitted and loom connected, then ignition switched on. NOTE, when opening the throttle check the voltage rises smoothly.




That's all for now, if I get a chance to test an A to B2 I'll do pictures for that too.
drp, SteveW and dastardly like this.
