with a faulty leak detection pump solenoid will that make the car smoke at times. White smoke, and mostly during acceleration? My fuel pump was just replaced but my check engine light has stayed on. Had it scanned....codes P0442, P0455, P1495 came up. Do I need to undo the battery to reset the computer?
P0442 EVAP leak monitored medium
P0445 Evap leak monitor large leak detected
P1445 Leak detection pump solenoid circuit
No this code condition will not make you car smoke at times specially at acceleration. The smoke at times can be from the engine using oil. Because you have a medium leak detected and at times a large detected all which deals with the EVAP system, check and inspect the fuel cap, fuel caps seal do wear .
Here a inspection of the fuel cap the seal here is worn, The fix and solution for most EVAP code are with the fuel cap, replace if worn.
