Yaris Tp System Performance Engine Code

[edli83]

Hi,

I have a 53 Yaris TSport with 80,000 miles on the clock.

I have recently been getting the Engine Light coming on intermittantly

I have read the Error Code and I am getting P0120 Powertrain: TP System Performance

Can anyone advise on what this means? The likely cause and possible solutions?

Many Thanks,
Ed

Throttle Position System.

Let the dealer check the throttle valve opening. You cant do it on your own beause you need the Toyota Tester.
