So driving home a few days ago, I get the check engine light with a code P0443. Mechanic is leaning heavily towards ECM, but based on some reading I'm ruling it out. The following is the list of events that occurred
P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P0161 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
P0443 - Evaporative Emission Control System Purge Control Valve Circuit
Check Engine Light Comes on at this point
P0135 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P0141 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0161 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
My mechanic didn't do anything and code has seemed to go away. Previously my mechanic replaced the Control Valve Solenoid, but refunded me since it didn't fix the issue. He checked for a short, didn't find anything. Checked fuse 47, no issues there. Any ideas?
