Odor Removal Tips for Erasing Musty Odor in Evaporator
Condensation, dust and pollen inside the evaporator case can cause mold to grow and leave a musty odor when the A/C is turned on. This musty odor can occur in all vehicles, not just Hondas, and it’s worse where there’s high humidity.
2002 Lexus Evaporative Emissions Diagnostics (Codes P0440, P0441 and P0446)
Anyone who works on an evaporative emissions code knows there are as many possible causes as there are ways to determine the failure, says Import Specialist Contributor Frank Scandura, who discusses the strategy he used on a 2002 Lexus SC 430 that came in with a check engine light and evap codes P0440, P0441 and P0446.
2002 Lexus Evaporative Emissions Diagnostics (Codes P0440, P0441 and P0446)
While old-school cooling system service often focused on coolant leaks and overheating engines, let’s begin thinking “new-school” by looking at modern cooling systems through the eyes of the engine coolant temperature (ECT) sensor. Coolant temperature is important because torque converter clutch engagement, idle speed control, variable valve timing, engine cooling fan operation and various other
New Innovative Snap-on EVAP Smoke Machine

DENSO Develops Cold Storage Evaporator that Limits the Rise in Cabin Temperature During an Idle Stop
DENSO Corp. has developed a Cold Storage (CS) Evaporator, which limits the increase in vehicle cabin temperature during an idle stop when stop/start technology is employed. The newly developed CS Evaporator is equipped with a cold insulator, located in the heat exchanging area, which stores cold energy to be used to cool in-vehicle cabin air while the engine and air-conditioning cycle is off in the idle-stop state.
Tool Tip: 10 Diagnostic Tests for Smoke Machines Besides EVAP
A smoke machine may seem like an expensive piece of equipment if it is just used for testing EVAP systems. But, if you factor in other diagnostic tests it can perform, it is a worthwhile investment.
