Intake Heater no voltage drop?

[Trophy Truck]

After installing my Smarty Jr. I threw this code twice now and cleared it. I goofed up and did not write down the code. Any input would be great. I checked the connections around the intake, and fuses.



Thanks, Pete

you usually only throw that code if the grid heater is called for and the ecm does not see a voltage drop while you are waiting for the wait to stop light to go off. if you do a grid heater delete and still wait for the light to go out . it will cause this. the 06 has a fuse link on the passenger side battery that feeds two solenoids, each one feeds a separate grid in the grid heater. if the fuse link go's bad or either solenoid does not close the ecm senses this and throws the code. best thing to do is get a grid heater delete and a cfm+ and do not wait for the wait to start light. if you think you really want to keep the restrictive heaters and need further help pm me and i will explain how that will require no test equipment
