Engine does not rev when pressing gas pedal

[pizza789]

I have a 2004 Sienna. I had to jump start it today (need to replace the battery). I have a "check engine" light on. Vechicle starts ok, idles fine. However, when I press the gas pedal - RPMs move up to 1100 and nothing more. No power, vechicle will move at about 2mph.

I checked for a clear air way - no problems there. I have not checked anything else as I had to leave the vechicle on the side of the road.

Ideas?
Thanks

Check for sensors that have fallen out of the air inlet hose. possible vaccuum leak

low voltage may have you in limp mode. try and charge/replace the battery and have your alternator checked then you can diagnose the problem better. it may solve your problem when you fix your voltage problem. The vehicles computer expects a certain voltage for the sensors to work correctly.

Thanks, I'll check these items. I can charge the battery fully.

I picked up a OBD2 reader today and found P2118 which appears to be a blown fuse for the accerater pedal. I will check this out tomorrow. It could be form when my son jump started the van perhaps he connected the battery wrong.
