We pull up trouble codes of (1222&1280)which comes up as interminent problem,i was thinking that maybe we have gotten some grud in connection and that if we use electrical spray&air
from one of those canned air for pcs that might get rid of the problem.
The ICP codes also came up on the garage scanner.

 

I would bet those were left over codes from your HPO issue. The ICP sensor is a tough sob and unless it has oil leaking into the connector your more then likely fine.

Hint...

Dielectric Grease on every electrical fitting every time you touch it.

 

Hi, 2 questions, (1) if i take battery cables off will that clear those codes
(2) if i were to spray ICP with a electrical spray then spray with canned air do you think that
might clean up connections as i think we might have got contamination on connections.
If so maybe why we are getting codes.
(3) Is it possible that pcm is reading these codes and sending phony info. to engine to run it.

 

No taking the battery cables off will not clear codes. Use electrical cleaner let it dry and use the electrical grease, no need for caned air. If the Icp sensor is not reading right the computer doesn't know how much oil it needs so it will make it run funny.
