2004 Toyota Corolla ProblemsCleaning May Correct Faulty Mass Air Flow Sensor
The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.
The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.
The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

2004 Toyota Corolla RecallsSeat Heater Wiring Shorts And Causes Fire
For vehicles equipped with aftermarket accessory seat heaters, the seat heater elements may short circuit when the seat cushion is compressed, and result in a fire hazard. Dealers will disconnect the seat heaters and refund the purchase price of the seat heaters free of charge to resolve the concern,
The airbag control module can fail prematurely due to electrical noise beyond the tolerance it was designed for. As a result the front airbags, side airbags, and/or seatbelt pretensioners could deploy inadvertently while the vehicle is being operated, increasing the risk of personal injury and/or a crash. Dealers will replace the airbag control module and front and/or side impact sensors as required to correct this concern.
This limited regional recall is for vehicles currently registered or first sold in southern Florida, along the Gulf Coast, Puerto Rico, Hawaii, the U.S. Virgin Islands, Guam, Saipan and American Samoa. Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. Dealers will replace the passenger side air bag inflator to correct this concern. If a replacement inflator is not available, as an interim measure, the dealer will disable the front passenger air bag and advise the customer not to use the front passenger seat until a replacement inflator is installed.
