throttle position sensor faulty
Has anybody had any problems with their TPS and had to change it, or do I have another problem, :head scratch:
I went for a ride yesterday the bike went great, when I hit the traffic near home the idle was all over the place when i opened the throttle it hesitated big time
would run ok mid range and hesitate again at 5000revs, It doesn't feel like fuel pump i have had that issue before.
I checked the TPS with a multi meter and it was way out and had trouble adjusting it (getting the settings right) I tried idling it at 2000rpm and adjusting it to highest revs, off idle was better but not anything else, put the meter back on and managed to set it (haven't taken it out since as we have a cyclone here at the moment) My bike is a stock B2 and if it helps it is black and gold stock except for a can and k&n air filters, they are clean, I feel it is the TPS as it is moving the trouble around when adjusted, the only other thing I have done is just before the ride I added some injector cleaner to the tank but the problem started after an 80km ride. any help thanks Craig
I had to change my tps as it was making the motor run very rich.
You might pull it apart and hose it all down with a good contact cleaner...
See if it will hold a setting after , you aren't out anything but a little time
If it doesn't work. ... Good luck...
I will give it a try today been studying the manual will check voltage at the ecu it is pissing me off i set it ok then but throttle response is shit house it is like the sensor isn't reacting quick enough Craig
how many miles on that tps.You ought to get at least 50k miles out of 1................A tps is a rheostat .The wiper and segments will wear over time.The only good ways to check them is testing with an oscilloscope or just replace with new for 125 bucks.
2002 zx12r b-1
I've got problems, can barely get to 70 mph . if in neutral for instance, opening up throttle to hold at 10,000 rpm it will not Rev over 5000rpm and bogs down to 2000 and back to 5 and back to 2. Terrible and depressing
its got 40000km or 25k miles to buy in oz $260 from the stealers if I get one from USA the shipment from part shop is about another $50 and not sure if it is the problem but thanks zx12mark Craig
I got one spare and as far as I remember ZX6R uses same than ZX12R (2000-models), not sure if B-model has same part number?
hi Div my wife is 1/2 Fin my 4 kids are 1/4 and grand daughter 1/8 so I live with 1 and 5/8 fins not sure about zx6r maybe I think part numbers are different how much you want for your spare Craig
Hi, pm me your details and I'll post it today(tomorrow)
Didn't find the part number, I recall you had to buy whole throttle body assy to replace one of these(just asking, why?)
And while you're at it, you could check the resistance on yours also?
yeah checked the resistance and within recommend specks but something weird when i twist the throttle Craig I sent you a PM
Im getting 5.06 volts to the sensor
the fuel pump is priming
No fault codes crankshaft sensor within required resistance
I have re set the TPS to 1.084 volts
My TPS reads 1.084 volts closed with fast idle off
when I open the throttle it gets to 1.99 volts at about 1/4 to 1/3 throttle and then shows an open circuit when closing the throttle it shown 1.99 volts at the same place and then counts down to 1.084 volts
the resistance on the TPS stays the same as you wind it around
the bike fires up instantly and then cuts out 1/2 to 1 second later
is it the ecu or tps anybody else have same problem
i haven't pulled the pump yet as I have a 1/2 tank of fuel and it didn't feel like pump when it played up I will check the strainer and pump tomorrow or later today
the bat is flat now on the charger will try again tomorrow
any and all help is appreciated and wanted thanks Craig :banghead:
yes it looks like that but I would think it should run at idle and bugger up when it flatlines (open circuit) sometimes you just need to buy 2 bikes the same
It will take a while to get another tps the spare one (98R1) had a resistance prob Craig
can I bridge the terminals at the TPS so the ecu thinks it is at wot to try and start the bugger this will give a constant return to the ecu of 5.06 volts
the wot setting is 4.61 volts SO will a bridge hurt the ecu￼￼￼￼
