EBV unpluged = check engine light

Hi guys,

1997 Cali PSD....I unpluged EBV at turbo to prevent any problems in the future and now I have a check engine light on. Anybody know how to eliminate the check engine light after unpluging the EBV valve on a Cali truck? I read a 1/2 watt 470 ohm resistor between the two wires would work, has anybody done this or anything similar?

Whats the reason for unplugging, is the sensor bad or the tubing fouled out.

could be a wiring issue also

Mines unplugged also, but I never got a CEL....

Also, I unplugged the MAP sensor for a test and never got a CEL...

I'm thinking my CEL is disabled...

I think that he is refering to the EBPV, not to the EBP sensor.

Yes maybe your CEL is diabled, if I unplugg the MAP sensor I get a CEL and with the EBPV unplugged = NO CEL.

If you have a CEL, Id scan it to look for codes.

The Cali will set a code when the EBPV is unplugged and the 49 state truck won't

If I'm not mistaken, www.dieselsite.com or Strictly Diesel Home Page sells the plug to go on the end of that to take care of the cel. But I may be wrong. You can use a resistor, but I'd be lying if I said what ohm. I know I've read it somewhere on here before, just can't remember where.

Found this at puredieselpower.com, I'll give it a shot.


94-97 7.3L Powerstroke Exhaust Backpressure Valve Terminator from DFUSER
[9497EBVT] $38.50




Did you gut your Exhaust Backpressure Valve?
Upgraded your Turbo Pedestal?
Easy to install.
DO not leave your factory plug hanging with open circuit.
Built for exact fit.
OBDII codes maybe detected and logged during a diagnostics scan of specific sensors by the PCM at start, when the Exhaust Back Pressure Valve is gutted or disconnected. The provided plug eliminator (Figure 1), used will stop the PCM from throwing the dreaded code.
This also will prevent the EBV from closing. It will always remain open.
For Instructions & More Info, Click Here

PLEASE READ THE DESCRIPTION CLOSELY.
THIS ITEM PLUGS INTO THE HARNESS THAT USUALLY PLUGS INTO THE TURBO PEDESTAL, NOT THE FRONT OF THE MOTOR.

Sounds like it should work. And doesn't require soldering or guessing on the resistor. They just made a convenient plug to terminate it.
