Modern Vespa

It's been a week or something my Sprint i-get check engine is turned on. At first it is turned on occasionally, but after a few days it's constantly turned on. Go to local Vespa dealer and had them to PADS this vespa. The error results are:

P1003 - Dirty throttle body - signal too high - ATT
P0031 - Oxygen sensor heater Voltage low - S.C. to Gnd, O.C. - ATT
P0261 - Low Voltage injector - S.C. to Gnd, O.C. - ATT

The mechanic told me that the Throttle body and the Oxygen sensor is broken and must be replaced.

Have you guys experienced such error on your Vespa? If so is there any other solution other than replacing the Throttle Body and the Oxygen sensor?

Thanks before

Update.

Today i go to not official Vespa garage to do a cleaning on the Throttle body.

Since they have a PADS after cleaning the TB they did a self adapter parameter reset and TPS Reset. It fixed the P1003 error.

Will try to replace the sensor to Fix the P0031 error code.

Hello friend
Did you solve your problem
Thanks

Hi Lads. Sorry for my English, I will try to explain whats problem do I have. Vespa GTS 125 iget. I have scanned DTC code and P1003 presents all the time, it is not possible to clean this error and one more error P0171 - Probe stuck on lean, this error i can clear.
Strange thing is that when you start engine eveything is fine, no check engine on dash (but acording diag DTC P1003presenting all the time, not possible to delete)), but after 2 min.(around) of engine idling check engine indicator is getting on and engine dies, on that time P0171 getting on.

Looking for mechanic hints......

DTC description for P1003 is - Dirty throttle body- signal too high
I have cleaned throttle body,(it was not dirty at all) -problem still on
I have replaced diffrent throttle body with idle sensor- problem still on
Replaced 3 different used lamba oxigen sensors - problem still on
Checked wireing, fuses.

Does anybody had yhe same issues?
Thanks for technical suport in advance.

Hi, did you program reset new throttle body?

No, i dis not reaet it.

When change throttle body you need To reset

There is no difference using original or other throttle body, errors are the same. I am not sure if it is possible to reset with my unit.

I will check tomorrow if is it posiible to do reaet. As i remember, throttle body is possible to reset up to 3000km with obdstar unit.

with my gts300 when I changed the throttle body (twice) I didn't need to reset

I did not change throttle body, the problem was check engine on dash after start ebgine and dtc code p1003.
Gts300 throttle body comes with ecu in one unit, iget have RISS ecu and throttle body seperatly.

Wipie, Your are absolutly right, I did TPS reset with my OBDSTAR unit and all mistakes gone. Vespa is running good again. Big Thanks to you and if you are visiting Latvia, very velcome to my workshop. Thanks.
