so when u goignt o acura diler and u want to do inspection if its something wrong with your car that what thay do is looking on this lights ? that how thay do that ?

ThanX

Acura have machines which display the same information in numeric form. Which is then easily translated on a chart. Having this information available to us is useless if you are going to an acura dealership because most charge $75 for a diagnostic (required because they never trust the user, and shouldn't) and then there are labor and parts costs to fix the problem.

If we know exactly what the problem is then we should take advantage of that knowledge and head to the nearest junkyard or Autozone for a replacement when appropriate. Also, there's nothing wrong with getting your local mech to do non engine invasive work I think. I had my timing belt changed right in front of me for 2/3rds the cost Acura would charge for labor alone.

Add code 36 to the list, it applies to GS models, possibly TCS on the Coupe models as well:

Code 36 - TCFC Signal (Traction Control Fuel Cut-Off)

"Hello Hector, The code you are getting is specific to the GS models. The code is for the traction control fuel cut-off. I recommend clearing the code and driving it some more to see if it comes on again. If it does, let me know and I can get you a copy of the test procedure"

Can anyone post instructions on where the pin holes are on a 91 ls, and how to do it, my check engine light has been on forever just no money to take it to the dealer, im hopefully getting a helms soon, so that prob. tells me how im guessing

Hey Trixiem

I had the same problem on my 93 LS coupe.

The ACG fuse is in the fuse box inside the car not under the hood

The fuse box is located inside the car located underneath the steering column on the drivers side

I know there is another way to reset the ECU without disconnecting the battery.

It involves pulling on of the fuses in the fuse box located under the hood.

Would someone care to comment ?

*bump* This thread is always helpful.

Does anyone know what it mean when your retrieve your codes and you get 4 long and 9 short blinks on the TCS light? Yes the TCS light and not the engine light!! this is code 49 but what does it mean?

My PGM-FI light came on the other day for about twenty minutes and then went off. When I started the car and began driving it lit up again after about 10 minutes or so of driving. I came home stopped the engine and then drove it again about 1 hour later. It hasn't come back on since and that was about two days ago. Should I be concerned or was this some weird electrical fluke? I am new to Acuras and cars in general so please if you answer please be as specific as possible. I appreciate any help. Thanks.

:p

Hello all. I am new to this forum but I've been driving a '91 Legend L Cpe for almost five years without any problems. However over a year the engine temperature indicator has been acting either weird or accurately like it would go up to half way at idling or low speed drive, then it came back to normal mark (2nd bottom one). Another thing when the high engine temperature was high was that the hot air was not coming out when I turned the fan on and adjusted the temperature selection to warm or hot during the cold season. Then I also noticed during the first few minutes after starting it up, the engine would rev up and down quickly (1k rpm- 2.5k rpm). After driving it for a few miles it stopped revving up and down at idle speed.

But for the last few months it has seemed to get worse as it revved up and down for a longer period of time after starting. The engine temperature has gone way up to the red mark almost 8 out of 10 times even when driving it at freeway speed, then if I turned on the fan and selected warm or hot air the scary engine temperature indicator would drop quickly to its normal operating mark and the hot air would come out of the vents. But it would do this either at the moment I turned on (or off) the fan and selected the hot air or after several minutes.

No engine check light ever came on. I stopped and checked the two electric fans when the engine temp. indicator was more than halfway mark and they did not run. The engine did feel a little hotter than usual but I am not sure it was going to overheat later. The radiator coolant is full and clean withou any leak. Everything else seems to be in working conditions but what has caused the engine temperature indicator to go high and back to normal after anywhere from first few to 10 minutes after starting up and driving.

I read the engine light codes thread that has a code 6 for engine coolant temperature sensor. I also searched for all temperature-related sensor parts (or thermostat) and found out so far there are two of them:

1) Water temp. sender
2) Thermostat (don't know for what use)

Would it be possible there is a faulty temperature-related sensor?

Any help will be greatly appreciated and sorry for the lengthly post.

where is the crank angle sensor?

AngelaTheLegend · 06-18-04, 02:50 PM

So where exactly is this thingie you have to jump with the paperclip?? I found the fuse, so I am half way there

I am having trouble with my acceleration...i think its the plugs (I am due at just over 120,000 miles) and probably the fuel filter (which is due as well). I've been putting crappy fuel in Angela (87 octane...yes i know

) but its sooo $$$$ here in CT!!!

I've got a code 9, number 1 Cylinder Piston Position. How do I got about fixing that? It's the only code that comes up. If I just reset the ECU, will that reset the position, or do I need to manually turn the piston? I've got a haynes and a chilton's manual, but they aren't helping. I'd appreciate any help from you all. Thanx.

In a previous post you mentioned the D4 light blinking to indicate a transmission problem. Are there codes you can pull from that signal as well to help pinpoint a problem. I have a 91 legend which is intermittently receiving blinking D4 - transmission warning light with erratic speedometer(intermittent also). Mechanic and transmission specialist (not dealer) can't find problem on the surface w/out going into transmission - big $$ on a '91 with 175,000 mi. Drives Great - could possibly be a sensor problem?

Yes, there are codes you can pull from a blinking D4 light.
Taken from the Helms:
When the PGM-FI/AT Electronic Control Unit (ECU) senses an abnormality in the input or output systems, the D4 indicator light will blink. However, when the Service Check Connector (located on the ECU cover) is connected with a jumper wire, the D4 indicator light will blink the problem code when the ignition switch is turned on.
Problem codes 1 - 9 are indicated by individual short blinks, while Problem codes 10 - 17 are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the problem code.
Let us know what code you are getting, and we can look it up for you. Chances are, it is your VSS.
