Got these codes this morning when I went to go for a drive. The car drove fine the previous weekend.

Between then I installed my new Deatschwerk pump and put the oem panels back on and tidied up the haltech harness.

Get codes on both the OEM ecu and Haltech. The throttle body does not open. If manually moved the feedback shows up in the haltech.

Car will idle but not rev. SES, SLIP, VDC off lights come on.

I checked the 15A fuse for the throttle body in the IPDM and it was good. Have not checked the relay.

I am wondering if it is the oem harness/haltech. The oem ECU should pull ground to turn on the TB power but either a loose pin or faulty relay is causing power to to be supplied.

any insight?

 

fixed it.

Loose pins on ecu connector...probably what is plaguing the utec owners.

Radio still does not functioning...ugh

 

Good to hear you fixed it! Yesterday my car threw these same codes for the first time. I was fooling around at a stop light and decided to turn my car off right before I came to a stop (damn light takes FOREVER). When it turned green I started the car and it would only creep along super slow. Didn't matter how much throttle I gave it. I quickly put my hazard lights on as cars were passing me (freakin embarrassing). I quickly restarted my car two times as it was rolling and it didnt help. I finally pulled over, turned the car off and waited 5 minutes. Started it up and it it ran normal minus the two codes. I have a UTEC as well but still don't know why it did what it did.

 

I have a very similar issue throwing code p1122 and p2135, SES, Slip, VDC off no throttle response, but running the v pro. Did you just reconnect the harness to seat better or did you have to repair the pins?

 

Nevermind I reset the code and everything is back in order. Hopefully it doesn't come back

 

I just got the exact same thing for the 2nd time last night. First time thought it was a fluke. Now im thinking there may really be a problem. Only afternarket ecu im running is Osiris and the factory ecumenical harness is still on the ecumenical with no aftermarket connections. So I hope the connection in there hasn't gone bad. What else could this be?
