Tip & How-To about Acura CL

Want to save an hour's labor charge if your Check-Engine light is on? (ALL cars 1996-present)

Note - this is only for OBD2 and up cars (1996 or newer) - it is fine for ALL cars even though it only is listed for Acura (the site doesn't let us select a "general knowledge" heading for cars.

Here's how to do it - when your check-engine light comes on, you have one or more faults that have set code(s) in your engine control computer. These codes will point to the sensor or area that is at fault, and are helpful (often necessary) in fixing your car.

If you take the car to a dealer or a shop to have them scan for codes, you'll be charged anywhere up to an hour's labor, even though it takes all of five minutes. Instead, go to AutoZone or Advance Auto Parts and have them scan it for you - just tell them your check-engine light is on and you'd like them to scan the computer for codes. They do it for free, and will give you a printout of the codes your car has set.

Now, go to the following URL:


Click on the logo for your vehicle, and find the code in the list that you have been given on the scan results sheet. If you are familiar with OBD codes and modern engine systems, this may be all you need. If not, come to this site and post the code(s) along with the year, make, model, and engine/transmission/drivetrain of your car, and one of the Experts here can further help you.

This way you don't get soaked by a shop or dealer for an unnecessary charge. Hope it helps!

scanner not communicating

no year, no joy. wow no year... what a pity.....
if 1996 and newer we use OBD2 scan tools
did you use a OBD2 scan tool, if yes state the make and model .
if car is older it uses OBD1, and you place a jumper clip and get flash codes out of the CEL lamp.
some 95s are OBD2 too, but we need exact year, and sub model spec on the Corolla.
The under hood sticker tells you what it is too.
saying Corolla is like saying vanilla.
see why here.
what country, yes, do tell that.
and what engine, i cant guess. you must look


before working car any car (engine or trans) know what you have.
if in USA< open hood, look up ,see that EPA sticker,
it even states what engine is in the car.

see list of engine here, its huge

83-1 permanent dtc ecm relation failure

sounds like an OBD2 comm failure, mine (i have 10) all show comm loss. but.. can be blown fuses killing OBD2 DLC pin 16 (not 12v)
also, of your car is newer and the scan tool is older, it can fail.
newer scan tools work on all cars here. in usa. all, obd2 1996 and newer. (i build oBD2 gauges and can go endless here... comms...)

no Pxxxx code?
what scanner?, there are many. some are junk.
is this a USA car, when posting nobody knows,
in fact, cars up to 2006 world wide, don't have OBD2 ECUs/PCMs.
not posting where car was 1st sold , is a failure.
if you are in usa, we can access the online FSM and look this up.
we use.

lets back up. (a real scan tool not a funky useless code reader)
you, make sure pin 16 is hot.
you plug in scan tool (newer) if car has CAN buss? the tool too must be CAN BUSS CERTIFIED.?
you key on. not started.
you push the scan button, no comm fails, you see TPS throttle angle.
and ECT engine temp and air temp and RPM is 0
all that not started enigne yet, if you cant get there, wrong car, wrong tool.
if the engine runs, the tool must scan, if not pin 16 dead.
or wrong scan tool.
