Question about Heating & Cooling
Short in wires from low pressure sensor on a/c.when wires are wiggled at
harness going to the ecm,the clutch on the a/c will engage.also the ecm
is showing 2 codes on the oxygen sensors which were replaced but it would still not pass a smog test in california.there was also a blown fuse
on the oxygen sensors which i replaced but the service engine light still comes back on.this to me looks like it could be in need of a new wire
harness.what do you think?
Try disconnecting battery & then remove connector @ ECM and clean all contacts at ECM & connector well with electrical cleaner. Check for loose ones & do as necessary (carefully) to tighten if needed. Add a little dielectric grease to connection before re-attaching & try that.
