So the title pretty much sums it up for me. I have a base model 04 TL. Its been my daily driver for 2 months and is great so far. I have some minor issues I'd like to take care of though. So I will just list them out and thank you for any help or advise you can give in advance. I do work with tools on a daily basis so I plan on doing the majority of the fixed myself, so any help in that department is much appreciated as well.
1. Bank 1 sensor 2 (o2 sensor) had the check engine light on. So replaced with a bosch replacement. But tripped check engine light again within 20 miles. Why?
2. Only driver side door speaker and tweeter plays consistently "loud". Others take awhile to "warm up". And still never seem right. Any ideas? I suspect the factory amp. Also suspect a previous owner allowed the interior to cook in a parking lot at sometime.
3. Had electrical system checked at advanced auto and was told that something was pulling a constant 1 amp draw on the battery.
4. Drivers headlight (HID).went purple/pink for awhile then flickered and went out. Bulb or ballast?

ANY help with any of these issues would be appreciated. So thank you.

 

Import? You realize your TL was built in Ohio right?

1.) No idea
2.) My guess is the amp is failing. There are threads about the amp needing some capacitors replaced.
3.) Check the HFL module. Is the panel above the rear view mirror warm even with the car off?
4.) Can't really help there either.

 

Mine TL would need a jump if it hadn't been started in more than 3 days. A guy in this article showed me how to bake it to fix the issue: https://acurazine.com/forums/problem...ing-up-831160/

Just did it today, so far so good.

 

Light probably burnt out. Easiest way to check is plug the good light in that circuit. o2 code probably caused by a vacume leak and it's throwing a o2 code. Just becasue a car throws an o2 code doesn't always mean its that.

 

What codes is that O2 sensor throwing?

 

Lol no I didn't realize that my TL was made in Ohio. But I think you know what I meant.
Idk the actual codes it's throwing. All I was told was that the bank 1 sensor 2 was reading as bad on the computer. I will look into the vacuum leak possibility.
Bad capacitors in the amp does make sense and would explain my issue. I'm thinking about upgrading that amp anyway.
I will be checking to see if the HFL module is keeping that panel warm today.
I've searched videos on changing the HID headlight bulb and they all show that the front bumper has to come off to change that bulb. Is this right? If so, that's awfully inconvenient lol.
Thanks again guys.

 

1. Bosch O2 sensors do not like these cars. You should try to replace it with a Denso or NTK/NGK Sensor. If that doesnt work you could have replaced the wrong sensor since theres two total or your catalytic converter is failing.

2. Amp is probably bad.

3. Hook up a multi meter in series to your battery and start pulling fuses. When your 1 amp draw disappears you have narrowed your problem to that circuit.

4. Your bulb is bad. When the bulb changes colors before it dies it indicates the gas is not effective at igniting anymore.

 

I was wondering if it was the bosch replacement. I know sometimes a universal replacement won't work for whatever reason. I'm sure the right one was changed. Although I do understand human error can still occur. I will probably get the denso version soon. Hopefully it's not the cat going bad.
Yea I figured the amp went out just didn't want to be the only one who thought so lol.
Will a clamp on amp meter work?
Just wanted to double check that it was the bulb. Never had HID lights before.
Thanks for the help!
