CCV Replacement - Engine Failsafe Prog

I just replaced my CCV. When I started the car, Engine Failsafe prog show up. Car is starting rough. Any information would be greatly appreciated.

Probably missed a connection or cracked a dead vacuum hose.

CCV Replacement DIYs

check your plugs and make sure they are all clean--throttlebody connection can cause the code your running into.

The car starts, but when I hit the gas, it would immediately die. Engine Failsafe Prog shows up and ABS light comes on. I will probably go back and recheck everything. I followed the DIY to perfection.

Check for codes and check for loose connections to the wiring box.

Do you know where I can get the scanner to read the codes? I don't have one. Also, where can I find a diagram for the wiring harnesses? Even though I took extreme care in identifying the different connections, there is a great possibility that I might have some wrong connections. I am trying to work on it today.

Since you're not in HI or CA, you can just borrow the scanner from AutoZone.

Or, for $30, including shipping & tax, you can buy your own scanner (I was borrowing one from a friend but got tired of that and just bought it).

From the bestlinks:
- Cheapest CAN OBDII scanner on the net that reads DTCs, pending codes, & clears codes
- OBD II PC freeware & $15 J1962 cable for the BMW E39

None of the local auto parts shops loan out scanners.. I went to a dozen local stores and no luck. I just ordered the one from Amazon that Bluebee mentioned. Now, with regard to the car, I did go back and recheck everything (literally had to do all over again). Still getting the Engine Failsafe Prog and the ABS on and the car dies when I press the gas. I still need to figure this out as time is running out or else need to tow it to my mechanic tomorrow. I don't want my first ever project to be unsuccessful.

Remove your abs control module plug, go for ride then update us.

Thanks. I will try. Where do I find the abs control module plug?

You know where you ABS module is? It's in the engine compartment right side. The plug is a huge one, to remove the plug you need to slide the lock clip slider, use a flat screw driver to start slide it out, once the the lock is fully slide out you can pull the plug straight up.

More than you want to know about the ABS is in this one post.

Tons more in the bestlinks thread.

Just do a find (control + f) for "abs"; use the "F3" button to skip to the next link. Hit enter to go to the link.

After much screwing around, the little hose that connects to the top of the throttle had a hole (very narrow opening in the hose that was hard to find). Now everything is working fine. Thanks for all the help. Next items on the agenda--fix the seat twist and do a cooling overhaul.

Could you post a pic of what you found? It could help others in the future. Was it at all related to your recent work? Did you bump it or move it, you think?

Bluebee: Thanks for the info regarding the "seat twist" and the "cooling overhaul". This is awesome.

Agent99: Sorry, I didn't take any pictures. I should still have the old hose sitting around somewhere and I can take a picture of the "hole-in-the-hose" and post it here. I am assuming this was related to the CCV replacement work I did in my car cuz everything was fine before I worked on it. I am not sure what I did--it wasn't in the greatest of shape in the first place when I was working on it. I must have yanked it out and broke it.

I echo that sentiment. We love autopsy pictures. It's a great example for others.
