#3246 of 3858 2005 Corolla "Harsh Shift Code"
Feb 24, 2009 (2:26 pm)
I have a 2005 Corolla. It had the Check Engine Light on ever since i bought it. When it was under warranty, the dealer replaced the O2 sensor thee times and the check engine light kept coming on. After, the warranty (36,000mi), the dealer told me to take a hike. Now the diagnostics is saying the main computer is bad which is warranteed until 80K miles. I have 83K miles and Toyota is saying "too bad". Doea anyone have any thoughts? Thanks.

I would imagine that the light will come on again soon if this problem persists. I might also ask for a notataion to be put in writing that you did bring the car into the dealer for this problem before your warranty actually does expire should the light come again after the warranty does expire..
#3248 of 3858 2005 valve clearance check
Feb 28, 2009 (5:30 am)
just wondering if anyone here has adjusted the valve clearances on their Corrolla. I do my motorcycles easy enough, but have not attempted any work on the Toyota yet.
Is it difficult?
ANY recommendations for a good manual?
thanks in advance.

Are you experiencing a problem that would necessitate valve adjustments?

According to the manual valve "adjustment" involves pulling the camshaft(s) and replacing out of adjustment lifters with new lifters of appropriate thickness - seems if this was ever required you might just as well pull the heads and get valve guides, cam bearings etc...

I have a 2002 with almost 100k miles. I hear valve clatter when I start the car up on cold mornings (40 degrees and below) but it goes away once the engine warms up. Should this be a concern and to have the valves adjusted?

If it goes away in 2-3 minutes I wouldn't worry about it.

The ticking noise you are hearing during cold morning start ups, especially in winter temps, even 45 degree weather with a heavier weight oil, often results in brief valve clatter noise during initial start up. Generally speaking, valves and overhead camshafts are the last parts of an engine to receive lubrication. The thicker the oil, the longer it takes to coat the metal lobes on cam and lifters. When lifters do not have a film of oil, you get metal to metal contact. Thus if you are using heavier oil in winter time, you will hear the lifters. Try switching to a 5w30 or ow20 if you are not already. Oil will get up to the valve train much more rapidly and keep valves quiet. This noise generally is not a harmful situation as long as it goes away, it's mostly just annoying.
#3254 of 3858 brake fluid light is on
Mar 03, 2009 (8:18 am)
just bought a 08 corolla. the brake fluid light is on all the time. the car drives fine. no problems at all. the car passed maryland inspection recently and the mechanic did not comment on the light. the car has about 20,000 miles on it
i checked the brake fluid and there is plenty of brake fluid.
What should be done about the light? does it indicate routine maintenance (oil/engine..)
Many thanks in advance for your help

If the brake warning light comes on it could be indicating that the fluid level in the master cylinder is dangerously low (due to a leak somewhere in the brake system). This light could also be indicating contaminated brake fluid. Adding brake fluid to the master cylinder reservoir may temporarily solve the problem. But if there's a leak, the new fluid will soon be lost and the warning light will come back on. Brake fluid leaks are serious because they may cause the brakes to fail! So avoid driving the vehicle until the system can be inspected to determine what's wrong. Leaks can occur in brake hoses, brake lines, disc brake calipers, drum brake wheel cylinders or the master cylinder itself. Wet spots at hose or line connections would indicate a leak that needs to be fixed. Leaking brake fluid can also contaminate the brake linings, causing them to slip or grab. There is a sensor in the brake fluid reservoir that could be failing that could also cause your warning light to come on. Regardless, this should be brought to the attention of your auto mechanic.
