Please I need your suggestion. Am currently working on a Toyota Avalon 2008. It was not starting so I did a diagnosis and got the error code P0335- Crankshaft Position Sensor 'A' Circuit Malfunction and P0102 - Mass or Volume Air Flow Circuit Low Input. I cleaned up the CKP sensor, same issue and I went ahead to replace it,replaced the air filter, I discovered the engine oil was very dirty and due for a change, I had to do that, the fuel filter was cleaned up. After all that the car came up, was fine for some time and went off again. I did another diagnosis and got P0393 - Camshaft Position Sensor 'B' Circuit High Bank 2. All this while the check engine light was still on. We noticed a cut on the cam shaft sensor and tried amending it. The car came up, was on for 15 minutes and went off again. Right now when you turn on the ignition all the dashboard lights comes up exclusive of the check engine light. What could be the likely cause?

At the moment we are having a problem with a warranty concern that we were not allowed to take care of and the dealer did all of the work with out authorization from us and now we have a bill.
There are 3 wires that have burns to the shielding one with 3in that has been pulled back and the other 2 have about 1/2in burn on the insulation. what is the proper TOYOTA way to repair this or is replacement of the whole wiring harness necessary.

A first time customer, referred to us by another customer, brought her 2003 Honda V6 Accord to us for a vibration problem felt through the steering wheel only at idle, in drive, with the car stopped. The vibration is more prominent when she begins to turn the steering wheel. The vibration is slight, but it’s there.
We did find a broken engine mount and replaced it. The customer says it’s “slightly” better, but the problem is not solved. We have gone thru the car with a fine tooth comb and found nothing else wrong. The car only has 50k on the clock and is in pristine condition and well maintained (I saw her records).
She said the problem started a year ago when the Dealer did a Power Steering flush and Transmission flush.
Does anyone have any ideas or help? Has anyone seen any issues with a vibration in the steering wheel after a Power Steering flush service was performed? Any help would be greatly appreciated.

We had a 2007 Toyota Sequoia with a complaint of a growl from the front while driving. You would bet money that the noise was from the front differential. In fact, we ran it up in the air in 4 wheel drive and you could hear the noise from the front differential. Or, what sounded like the front.
We took it out of 4 wheel drive, and ran the real wheels only. The tech inside the car shouted out of the window, “The noise is still there”. After listening to the rear differential, we found that the noise was actually coming from the left rear. We pulled the bearing apart and it was filled with rust and scored.
The left rear bearing solved the problem, but we got initially fooled.
Just thought I would pass this info to everyone...

Toyota Cleared of Unintended Acceleration???
Federal Highway Safety Officials on Tuesday of this past week absolved Toyota for problems pertaining to unintended acceleration with respect to its “electronics”. As Toyota cheers this finding, the news media now reports that according to the National Highway Traffic Safety Administration: Driver Error is the cause for most cases of unintended acceleration. That’s right, MOST cases. All that was cleared in this investigation, which NASA also participated in, was the electronics systems of the Toyota vehicles.
No conclusions were reached for the mechanical issues Toyota has with either the floor mat or the gas pedal. Many news stories failed to report other parts of the investigation. Here’s a quote from the Wall Street Journal, “In a few cases of prolonged uncontrolled acceleration, NHTSA said slipping floor mats that trapped the gas pedal were the likely the cause” Here is a direct quote from Mr. Ray Lahood, US Secretary of Transportation, “ The evidence points to mechanical and driver problems, not electronic”. And, the last quote for today from NASA’s lead engineer Michael Kirsch, “An electronics failure couldn’t be entirely ruled out”. For me, there are still a lot of unanswered questions.
Three main causes for unintended acceleration were found, Sticking gas pedal, floor mats that trapped the throttle and driver error.
I don’t know how you feel, but for me the jury is still out. I know firsthand that I had customers complaining of run-way Toyotas long before the problem hit the news papers. And, if this is driver error then why only Toyota vehicles? Wasn’t it Toyota who finally admitted to the problems?
Please, I want to hear from my fellow shop owners. What do you think?
