I got my DCRH + TYpe S midpipe + Greddy Evo2+ Casper sim ( Secondary 02)
Now it's giving me a CEL (p0134) No activity found on Primary. WTF?
What should i do to fix this.........i know my 02 sensor are ok before i put on my DCRH and it has low miles on it.
IS this a COMMON PROBLEM with ppl using DCRH even with Casper sim?
Would it affect my Engine?
Gas Mileage?
I reset my ECU already, after 0.2 miles......CEL comes on!
How can i turn this off?


Any help will DO!!!!
thanks

did you install the RH and the sim at the same time or one after another? If you ran catless for awhile and then put the sim on it could be bad. I had to replace my o2 sensor twice, and this was with the sim.

 

i've put my whole setup at the SAME time.

 

yay. primary sensor failures are expensive.

 

Had you tried using a mechanical 02 simulater??

 

Hmm...

So you've installed the sim on the secondary sensor -- but the error is for the primary air/fuel sensor, right?

I know...that's why im trying to fix it .....IT's so EXPENSIVE to buy a new one!

 

May have to buy a new primary sensor, then. Either that, or locate a used, working one somewhere. I don't think the Casper sim had anything to do with it since it was on the other sensor.

 

long as you didn't install them backwards your fine. Another thing that happened to me during install was the the tech installed them backwards, and it fried my ecu. CEL stayed and wouldn't clear. Had to get new ecu and started from scratch.
