He would check line pressure and or pressure for different applications of trans like accumulator or clutch application. Also because of dealing with transmissions on a daily basis could probably tell you what is specifically wrong with it as most mechanics like me don't do a lot of auto trans work due to so many other things that go wrong with a car that we have to fix.

I have a 05 Acura Tl engine light on, has a code of P2240. 02 sensor bank 2 sensor 1. So I replaced the o2 sensor on exhaust manifold by firewall like the book says, cleared the code and the engine light came back on same code P2240. Could it be a bad new sensor or another problem?

To change an oxygen sensor (o2 sensor) you just unplug it, and unscrew it from out of the exhaust pipe/manifold, and replace it. Also, if your up to it, the mechanics that do the repairs for the dealers, will do work like this on the side, for like fifty dollars, to change an oxygen sensor, all you have to do is ask them. Pull them to the side, and ask them. Because of the difficulty, there are really no instructions to do this because you just unplug and unscrew.

TL P1172 Bank 1 sensor 1 is out of range. I bought the sensor online. I need to know exact location of this sensor on the car. How do I get to it? Is it under the hood or under the car? Are there any instructions available online? Are there any photos available? I would really appreciate any help.
Thanks,
Nedu

Got it fixed, did the wrong one first. Look at exhaust diagram on here posted march 30,2010 and it shows bank one at front of car and it is not bank one is at the firewall where cyl 1 is. So replaced the o2 sensor at front and is bank 2 sensor one upon buying a manual. Tell legitmate007 that diagram is wrong for a Acura TL 3.2 Thanks for the help!

Here you go, it should be fairly easy to do because it is right in the front of the engine.

While driving the TCS light comes on followed by Check Engine light. After restarting TCS lights is off but Check
Engine stays on. Code is telling that EGR valve have a problem. When you reset a computer, sometimes you can drive for days and then it happened again in the same sequence: TCS first then Check Engine light.

I don't think it's brake related, becuase sometimes it happened when I am braking, but another time when I am just cruising with my foot off the gas pedal.

Hi maaiig,

The TCS light can be turned on by and engine problem and in this case, it is the EGR causing misfiring.

You need to get the CEL problem checked and rectified first as engine trouble codes takes precedence over other codes.

What is the EXACT trouble code and have you done any repairs to it yet?

I replaced the sensor (bank 1 sensor 1) with part number BS13965 oxygen sensor but the check engine light is still on. I try to rest it by unplugging the battery, the light went away for about five minutes but then came back. I am not sure why. Is this the correct replacement part? I would appreciate your help.

Thanks,
Nedu

When EGR has a fault, it is not as simple as cleaning the valve and replacing the gasket. The port under the EGR has to be cleaned to clear the clogging due to carbon build up.
