2003 Toyota Corolla Problems
Cleaning 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.
Check Engine Light Due to EVAP System Fault
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.

Sound When Driving Over Bumps May be Struts/Bearing Plates
If the vehicle develops an annoying, clunking sound when driving over bumps it is usually the struts and strut bearing plates. These may need replacing at 100,000-125,000 miles or sooner. If the noise is a more of a squeak or groan, it can be usually be eliminated by spraying a light lubricant on the suspension bushings 1-2 times per year.
Engine Won't Crank Due To Starter
If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.
Window Won't Roll Due to Loose Regulator Mounting Bolts
The bolts attaching the front door window glass to the window regulator may come loose. This can cause the window regulator to become damaged and possibly causing the window glass to break. Some 2003 & 2004 models have been recalled for the issue.
Reports of Daytime Running Light Problems
There are occasional reports of daytime running light problems.
