Toyota Camry Ignition Coil May Fail After 100,000 Miles

Toyota Camry Problem
19 Reports
Me Too

Model Years Affected: 1998, 1999, 2000, 2001, 2002, 2003, 2007

Average Mileage: 124,715 mi (13,300 mi - 200,000 mi)


On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

    So far I've had 2 coils replaced and now it's only about 2 months later I'm getting another reading that another coil has failed. Never had this problem with any of the other cars I've ever owned for over 30 yrs. Back to the dealership tomorrow and feel they should fix this problem once and for all at their expense. If these coils are defective, then Toyota should foot the bill!

    Do not pay a mechanic to replace these coils, it is two nuts and one bolt to do it yourself. Remove the plastic cover over your engine block (where you put oil in the engine, it is two 10 mm nuts), underneath you will find your coils, either four or six depending on whether or not your engine is 4 or 6 cylinder. The bolt in the coil is 10 mm also, as you look at the coils they are numbered from left to right, #1 coil is all the way left if you are facing the engine. Unplug the wire harness from the back of the coil, pull up on it and it pops right out (your spark plugs are underneath it FYI if you want to change those yourself also, one plug under each coil).

    So with a 10 mm wrench, about $100 for the part and 5 minutes of your time you can do this yourself. Sorry to all of those that were fleeced by mechanics. $300...sheesh!

    I have had all the ignition coils replaced twice and some three times in the last two years and am continuing to still have problems. The check engine light will come on and it will die without notice or will run rough. Each time is taken to the mechanic it is the ignition coils and usually only one cylinder each time.

    I have had multiple failures of the ignition coils since I've owned this car brand new in 2006.

    The car had previously been serviced 3000 miles before, and this is second time the check engine light went on. The OBO device showed the code problem as P0300, P0302, P0303. The car is not driven that much, so it was suspected that maybe the gas in the car was gummy, or caused internal parts to be clogged.
    Previously, the spark plugs had been replaced, as well as the spark plug wires.(@ 3000 miles ago)
    Mechanic indicated that upon removal of the sparkplugs, cylinder # 3 spark plug was dirty and burned and ignition coil looked bad. This is after 3000 miles of driving. So he recommended replacement of the ignition coil. I do have to say that the car is 15 years old, so at that age, I can see that a lot of the car's parts are beginning to fail as they probably have a lot of dirt on them, and if they are plastic, probably the age and heat in the car is means they crack etc.

    All of a sudden lots of vibration. Thought it was the road at first but then started losing power.
    Made it home and to repair shop but it felt very wrong to drive it like this.
    Replaced just the bad coil. $300
