2004 Toyota Corolla Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2004 Toyota Corolla

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 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 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.

I am the original owner. It has been well maintained. It was in one accident in which there was front end damage, but we have had no problems with it since. It is currently used as a 2nd car by my HS and college-age children. The other option is to use the $1500 on another used car.

how could the transmission need to be replaced ? is rebulid better than replace ? I thought toyota was a good car ? I put fluid in and all came out why ?

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.

When deployed, excessive pressure can build in the passenger front airbag. This could cause the inflator to rupture, increasing the risk of personal injury to vehicle occupants. This recall affects both originally installed passenger front airbags as well as those that were installed as replacement service parts. Toyota and General Motors will replace the passenger front airbag inflator on their respective vehicles involved in this recall.

This is a great car with excellent gas mileage. I have about 71k miles on my corolla and I have not had anything problems with it.

has worked perfectly for 102K miles, so far. The only thing that died was the radio/cd player, at about 80K miles.

I have a 2004 Corolla LE with 237,000 miles on it. there has only been one issue, the AC stopped, the fan still worked. I looked online and found some info about a relay that would occasionally fail, I went and got one a local parts store and replaced it. 2 hours and $13 later it was all better! This car has been a real trooper and I have no idea what I would replace it with, whenever that time...
