Check engine light in my da
ok so i washed my egine with some degreaser. and a lil water go down by the plug not a big deal got it out. but then i was driving today and got on it a lil bit and te check engine light came on. i tried reseting it but that didnt work anyone i have any idea what i think it may be a vaccum line but then again it could be a host of things. think it would be worth the $85 to get it diagnosed?

Re: Check engine light in my da
When the Check Engine warning light has been reported on, turn the ignition on, pull down the passenger's side carpet from under the dashboard and observe the LED on the top of the ECU. The LED indicates a system failure code by blinking frequency. The ECU LED can indicate any number of simultaneous component problems by blinking seperate codes, one after another. Problem codes 1 through 9 are indicated by individual short blinks. Problem codes 10 through 44 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.
you have to jump a service connector located on the passenger side right under the dashboard near the door. The connector has two pin inputs. Connecting them with something like a paper clip will force the check engine light on the dashboard to display the codes. when u pull the kick panel on the right side floor board where your ecu you there will be an extra plug hanging i beleive its green or blue, put the paper clip in it, turn the ignition to the on position and count the number of blinks on the check engine light.
codes 1-9 are indicated by a series of short flashes; two digit codes use a number of long flashes for the first digit followed by the number of short flashes for the second digit. So a code 43 will be represented by 4 long and 3 short flashes.
The position of codes in a sequence can be helpful in doing diagnostics. A display showing 1-1-1-pause-9-9-9 indicates two problems occurring at different times. A sequence showing 1-9-1-9-1-9 indicates two problems occurring at the same time.
