That means you have a failure in your EVAP system which is your fuel tank and supply, return lines and canister. Make sure your fuel cap is on correctly and tight if that is OK then you will have to have it diagnoised.

Po440 confirmed po440 pending why would it say that


Some fault codes require multiple stop/start cycles (operating the vehicle) before it will throw a check engine light. When the code says it is pending, the ECU has detected sensor values beyond the norm. It will monitor the systems and if the problem doesn't go away (the ECU continues to see erroneous values) it will confirm the code and turn on the check engine light.

2001 chevy tracker code po455 and po440


If your check engine light is not on and codes are present, your dash bulb that illuminates the check engine light may be blown. I would have them clear your codes anyway and drive the car for a day or two. then have them recheck the codes. if nothing, your car will pass

Service engine light comes on


This GM's definition of this code:
P1404 - Exhaust Gas Recirculation (EGR) Closed Position Performance
The most common reasons are either the EGR valve position sensor is defective, or the EGR valve is not fully closed due to carbon.
