i pulled out of garage and my the check engine light came on and the cluster showed reduced engine power. it would not rev above 1000 rpm
and was popping out of the exhaust
i have 2003 silverado ss and have had whipple installed for about 2 weeks
no other mods
the code was p1518
i tired a couple of things and i wiggled the whipple computer connector
and seemed to work normal after that.
please help what is this code and has anyone else seen this ?

 

DTC P1518 Electronic Throttle Module to PCM Communication. ive seen the reduced engine power but it was caused by P1514

 

It is the whipple (junk) computer.....pull it out, add injectors and a tune. You will be happier.

 

once i programmed a used superchip programmer on my whipple charged truck. what i failed to ask teh seller was if it was for a electronic throttle or cable (mine is cable) Well. as soon as i programmed it i got the reduced engine power and wouldnt even idle. Its amazing how much of a difference even misconnected throttle bodies can make.
