Question about 2000 Chevrolet Silverado 1500
Dealer wants 610.00 dollars to replace, reprogram ecm and for some reason wants to do fuel induction flush?
this is on a 2005 chevrolet colorado 3.5l 32700 miles...they say part is 100 dollars and not sure about cost to reprogram ecm...I have talk to other mechanics they think price little high, and do not think flush has anything to do with fixing this code, but they cannot do cause they do not have capability to reprogram ecm...any thoughts?
thank you, jerry
Yes the evap and fuel injection flush service are 2 diff things, replace the evap solenoid and clear the code, also make sure the vent on the carbon canister is clear.

Evaporative Emission Control System Vent Control Circuit Malfunction
What does that mean? Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.
Symptoms There will be no obvious symptoms to driver, other than MIL illumination.
Causes A code P0446 could mean one or more of the following has happened:
