PCM Codes
Hey yall. Newbie to the site and I am getting the dreaded 1131,1132 and 172 codes.
2001 Expy, 5.4, 137k miles, rebuilt tranny 8 mo ago replaced o2 sensor damaged on tranny work. original MAF. New plugs all oem replacements.
I searched the site and it looks like I am gonna be in search of a vacuum line. Is there a specific one that could be damaged in a tranny R&R? What is the easiest way to find a leak.
Thanks,
Blake

P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1.
P1132 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 1.
You're not looking for a vacuum leak-you need to replace an o2 sensor.
