Getting a BD X-flow intake elbow, would like to do a heater grid delete I've seen on previous post that when the wires are left unconnected some are getting engine codes. What is the best way to prevent this? As I remember someone also came up with a large resistor to prevent the code is this a good way to attack this problem
Your feed would be greatly appreciated Thanx

Besides following summer around the globe, I am hoping the Smarty makes an option to have it disabled.

ive had mine for a couple of months and it has never thrown a code

It does store a code but it does not illuminate the CEL. If you use your Smarty or a good OBD2 reader you will see it. Since it does not make the light come on, I dont really care about it.

ive used smarty and an obd2 reader and there is nothing

So...just un hook the wires at the grid...or also back at the baterry?

matego

Unhook the wires at the solenoids and at the grid heater. I removed all the wiring too just to clean things up a little. If you just unhook the wiring at the heater and tape it up you risk shorting it out.

I know my truck and one other that keep the code but I now forget what the number is. They are both 05's if that makes a difference.

I wonder if the soleniods can go too? How far back has anyone removed this sytem without issues.

I think I am really at a point I need to lose any restriction in my airflow...no matter how small.

matego

The solenoids are mounted beside the passenger side battery. They have nothing to do with airflow. I believe if you disconnect the solenoids it will throw a code for open circuit.

My intake horn incorporates a heater delete and should be restriction free. I am not sure what your horn is like but I did notice a difference at my power level getting rid of those restrictions.

Mine does not throw a cel and it is all gone. I removed wiring, solinoids, heater and pass. side battery. The code is in the ecm but the check engine light has never lit up. Tim

I get two codes in the ECM from mine being unplugged, but no CEL. I can't remember the numbers but they are Heater Low Voltage 1 and 2. I have the two wires off at the grid heater (obviously) and I have the solenoid unplugged from its trigger wire over on the battery box. All of the wires are still physically under the hood, however.

Thanks Tim...my air filter might be easier to get to now!

I didnt even think the computer looked at the heater grid unless it was cold enough for it to work.

If I turn my key straight to start in the morning there will not be a SOFT CODE, but if I hesitate at all it will throw a SOFT CODE. SOFT CODE is where the computer see's something abnormal but not enough to throw a CEL. About every 2 months or so I will go in and clear it out!!!
