If fuel doesn't fix it, he said he'll have to keep the car while he discusses with Toyota on further testing to locate the problem.

I will continue updating once I finish this tank and get a fresh tank.

Did the car return to normal mapping? Is it still in safe mode? I would imagine that once the indicator was removed it would have, just asking for clarification...

No, the car is STILL in safe mode. And a DOG in the morning when it's cold. I kept driving this evening to burn the gas off, and refilled with fresh 93 today. Hopefully by tomorrow evening I should burn through 1/4 tank and I'll know more. I hope it is good news.....

Bad gas causes knock on only one bank? How does that work? Also, I thought there were knock sensors for each cylinder, perhaps I am wrong. Anyway keep the community updated as this progresses. Thanks for posting

The Tech told me the engine is "very sensitive." In response, a co-worker asked if the engine was PMSing.

To answer your question......I have no clue......

*UPDATE*

The master tech at the dealership is sending my data dump to Toyota tomorrow to get their input on the issue. He said they should have an answer to what to replace/do by tomorrow afternoon. He's also hoping it's just a knock sensor, and he expects it to be a standard Subaru sensor.

Abner, that is crap... Much like ahauseer stated bad gas would effect each individual cylinder, not just one side. I still think it is a bad knock sensor, however keep your head up toyota will take care of you. I still can't wrap my mind around why the car is still in safe mode??? It would have to be an ongoing issue to keep the car in safe mode, fortunately that also points to a faulty sensor. I can't believe some of the dealership mechanics nowadays, they understand how to pull a code, read a manual, but have completely loss the ability to trouble shoot, Sad really.

Yeesh.

First model year woes... probably an overly sensitive knock sensor.

Good luck.

The master tech working on my car seems very knowledgeable. However, he seems hesitant to swap the sensor without Toyota's approval since it is a first model year. Today is day 3 that the data has supposedly been at Toyota for analysis, and still nothing. I'm getting anxious. I might stop in and have the tech swap knock sensor between the banks to confirm it IS the sensor.

You may want to ask him to pull the sensor and check for continuity, that will tell him if the sensor is bad without having to install another one, or swap the other sensor around.

As a sad update, my car has been at the dealership for 1 week. Toyota sent an engineer to "inspect" the car last week, and found nothing. His final suggestion was "it's not the gas, replace the knock sensor." WOW! I could have told them that!

So the knock sensor was ordered, and arrived today. However, the dealership won't install it until tomorrow morning. So if the knock sensor does NOT fix the problem, and something else needs to be ordered, there's another week.

Am I pissed? YES! It's been almost 3 weeks since the problem occurred. The dealership doesn't seem to be in a hurry, and Toyota doesn't seem concerned. If they have to hold my car beyond tomorrow, I will go from frustrated customer to irate!

On a plus/minus note, they gave me a 2012 Scion tC to drive. Plus because the car is free. Minus because it's a tC!!

how do you read the error code?
How do you put car on Safe mode?

Use cheap obd code scanner like this Android Torque software is good.

Car will go into "safe mode" when the ECU or possibly the Transmission computer detects a significant problem or a sensor failure in an attempt to protect engine/trans from further damage. limits throttle and rpm to about 3500 rpm.

Won't go back to normal till fault repaired and ecu reset (battery cable removed for short period)
