Check Engine and TCS Lights on at the same time

[terrypancake]

Yesterday my Check Engine light came on, with it, the TCS light came on. At that time the lights came on the TCS light wasn't flashing. When the TCS light came on it stayed on for 20 minutes on then it went off. It currently is off. Last night I went for a short drive after I got home saw the light blink 3 times. I printed page 6-12 from my service manual on CD (thanks SkyGuy). The Check Engine Light code for 3 flashes tells me, if I am correct, would be the MAP sensor. Are the 2 light related? The car has 43,000 miles and I am scheduled for the 30,000 mile check on Tuesday. Just wondered if this is as common as the EPS light on my 95? The EPS problem is going to be fixed Tuesday.
I just went to the car this morning and started it, No TCS light with the engine running. The Check Engine light is still on and I waited about 3 minutes and the Check Engine light never did flash. How long should I wait before seeing any codes flash?
Thank you in advance.
Terry

I just did the 7.5 amp Radio Fuse Reset. went for a 4 block drive, no check engine light anymore and the TCS appear to be working normal. I am not going to be able to drive the car for a few days. Do you think I'll get to see these light on my next drive?
Could there be something in my system, ie battery, that is causing the goofy light combo's?

Now that's the first time I heard that you get a CEL code without bridgeing the service connector - I wouldn't take this as a serious code reading.
BTW: If you have a U.S. car you should have a OBD I or II connnector which may give your Acura shop a lot of hints. And the ECU reset is not the radio fuse but the clock fuse.

Doh! That is really what I meant. I think maybe I had read you lose the radio presets after pulling the clock fuse and had that on my mind.
I am getting it to the dealer Tuesday so they can figure it out.
Thanks Racer.

I just went for a test drive with new headers installed, and the same thing happened to me - both lights came on. I did replace o2 sensors as well. The car felt like it loaded up, then at 4,000rpm would take off. After about 10 minutes of driving, both lights came on. I shut the car off, retarted and the TCS light stayed off. I pulled the clock fuse and that reset the check engine light. I'm wondering if the computer is "relearning" the new o2 sensors? I'd blame the loading up on something fowling the sensor, but they are new, and I did'nt use anything special while installling them. I'm really pleased with how the car feels...I'm hoping this was an isolated deal.

I have the same problem, both light just came up. Here is my thread.http://www.nsxprime.com/forums/showthread.php?t=56789

Check your main relay by knocking on it. You will hear a clicking sound if the soldering connections in the main relay are no good anymore. If so, resoldering will fix the problem.

Can you tell which relay?

The black box next to the ECU.
