P0440 Question
I am working to resolve this on my 01 Bravada, and have reviewed the sticky by Swartlkk (https://blazerforum.com/forum/diagno...plained-35145/) and had one question on this post....
Swartlkk states:
Check for the following conditions:
* A loose, missing, damaged, incorrect or improperly installed fuel cap
* Missing or damaged O-rings at EVAP canister fuel vapor and purge line fittings
* A cracked or punctured EVAP canister
* A damaged or disconnected EVAP purge line, vent hose or fuel tank vapor line
* Incorrectly routed or damaged EVAP system purge and vapor lines
* A poor connection at the VCM. Inspect the harness connectors for the following conditions:
* Backed out terminals
* Improper mating
* Broken locks
* Improperly formed or damaged terminals
* poor terminal to wire connection
* A damaged harness - Inspect the wiring harness to the EVAP vent solenoid, EVAP purge solenoid and the fuel tank pressure sensor for an intermittent, open or short circuit.
* A kinked, pinched or plugged EVAP purge or fuel tank vapor line - Verify that the lines are not restricted.
My questions is, which locks are being referred to? Assuming this is the clamps for the fuel lines or the rin lock that holds the fuel pump in, but want to make sure I am reading this right and not missing something. I have checked my gas cap and even replaced it with an AC Delco cap.
Sorry of this is an ignorant question....thanks for looking!
