Yaris won't rev above 2000 rpm

[Richiejnr]

Hi I have a 2007 1.3 yaris I have just changed engine and now it won't rev above 2000 rpm. I have the following fault codes coming up p0121, p0113,p0121,p0122,p2135  

Cod anyone shed any light on this think it must be an electrical issue somewhere just not sure where 

[jonquirk]

Searching against the codes suggests a throttle body problem, or the wiring to it. Are all the plugs seated properly?

[flash22]

most of them are TPS related what year car did the engine come from ? i would do a throttle position relearn or swap the throttle body from your old engine to the new one

[Richiejnr]

From same year I put the throttle body from original engine on and no difference 

[flash22]

clear the codes and see what comes back ? New or old engine loom ??

[Richiejnr]

Cleared codes same codes came back it is the loom that belongs to replacement engine 

[flash22]

What was the issue before the change ? Burning oil/timing chain ?

Were both throttle bodies clean?

Try the electrical connector, disconnect and re-connect making sure you here a resounding 'click' when pressed home.

When swapping the TB did you disturb the 'gate/flap when it was powered up?

Got it!!!! It was a bad connection in the plug into ecu fixed that and running sweet as a nut. 

 

Thank you everyone for your advice 

[stantheman1]

The 'thanks' is for reporting back on the fix.

The chain tensioner gave up the ghost
