I can't send you the information that I'm using because I'm not equipted with a scanner to copy it over to you..but I would be happy to help you with this if I can..the best I can do is give you the info I have on it..Code 128-351 refers to the turbo inlet air sensor..its a two wire sensor in turbo air intake..The info is as follows
troubleshooting flash code 29...
turn ignition on, start and run engine for 6 minutes-check diagnostic reader for codes.. if any other code other than 351 or 404 are logged, troubleshoot this code first..if no other codes are present, then proceed to check sensor..
Unplug tci connector and measure resistance between cavitys 1 and 2.
If measured resistance is greater than5 ohms check for open sensor..We would have to take it from here after check is complete..If this does not satisfy your question, let me know and I'll open it up to someone who may have better capabilitys with materials than I do..Thank you..
