95 sl500 check engine light reset and comes back on after it sits over night. any idea?


What code is it throwing ? Some codes are what are called two trip codes ! You clear the codes an start an drive the vehicle ,no check engine light . Park the vehicle over night an bam next time you start an drive the vehicle the check engine light comes back on .

??There are two types of DTC's, 1 trip DTC's and 2

trip DTC's

??A 1 trip DTC is for a condition that requires

immediate attention such as a catalyst damaging

misfire.

??A 2 Trip DTC is one that a condition must be found

during 2 consecutive trips such as an EGR fault.

??Most Monitors do not set a DTC and light the MIL

when a vehicle fails a test for the first time during a

DRIVE CYCLE. If a test is failed on a second

consecutive DRIVE CYCLE the MIL will light and a

DTC is stored in the vehicles powertrain control
module (PCM).

Hello
When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

O/d light blinks when driveing o/d seems to be engaged car has 198000 miles and runs very good also engine light is on


O/D light blinks, but with that the check engine light is ON.--- This will make your troubleshooting easier.When the check engine light comes on, and remains on, this indicates that there is error stored in your cars computer.---- Once the computer is scanned, you will get error codes, as per that error code it will point towards faulty part, which is causing the O/D light to blink.-------- Most probably the O/D light blinks, If a problem exists in No. 1 or No. 2 solenoids or speed sensors .
--------------- For car after 1995 it requires OBD2 tool and for car before 1995 it requires OBD1 tool.------- --------- You car will require OBD1 tool.There are very few auto parts store and repair centers who have OBD1 tool.In your case you required OBD1 tool.------ You can just contact local auto-parts store and they will guide you to the nearest store who has OBD1 tool.There you can get your car scanned.If there is error set in your cars computer, then you will receive the error code.As per error code it will point towards the faulty part causing this problem in your car.------------- -------------- The codes which you get is scanning will be mostly any of this following codes:--- DTC P0500 - Vehicle Speed Sensor Malfunction
. DTC P0750 - Shift Solenoid "A" Malfunction
. DTC P0753 - Shift Solenoid "A" Electrical Malfunction
. DTC P0755 - Shift Solenoid "B" Malfunction
. DTC P0758 - Shift Solenoid "B" Electrical Malfunction
. DTC P0770 - Shift Solenoid "E" (SL) Malfunction
. DTC P0773 - Shift Solenoid "E" (SL) Electrical Malfunction
. DTC P1520 - Stop Light Switch Signal Malfunction
. DTC P1705 - Direct Clutch Speed Sensor Circuit Malfunction
. DTC P1765 - Shift Solenoid Valve SLN Circuit Malfunction
. DTC P1780 - Park/Neutral Position Switch Malfunction
--------------- Now it all depends on what code you get, as per that you can replace the following part.------- This will help.Thanks.Helpmech.

Check engine light comes "on"


OK, If I understand your question correctly, Your Check Engine light is coming on and you are getting a Diagnostic Trouble Code (DTC) P0240 and we are talking about a 2000 Honda Civic DX with a 1.6L engine? If this is not correct, please let me know.

DTC P0240 is not a valid code for the vehicle listed above. Are you sure we are not talking about DTC P0420? If this is the case, then your catalytic converter is not working and most likely will need to be replaced. If you previously had fuel system problems, this is what most likely destroyed your catalytic converter - especially if the vehicle was driven fo some time with the fuel system problem. It is VERY common for this code to come up after other engine performance problems have been repaired. The reason for this is because the computer will not run the catalyst monitor if there are other problems in the ignition or fuel systems. So as long as these other problems exist, the computer has no idea what the condition of the catalyst is. Once the other problems are fixed, then the catalyst moitor will run. If the computer finds that the catalyst has been damaged and is not performing as designed, it will set DTC P0420.

Maintenance light


most cars have maintenance lights,. it is a great way that the factory gets you back to the dealer at regular intervals of 30,60,90, 120k miles - check your odometer,. sometimes just driving a few miles will shut off automatically, otherwise an obd2 reader could reset the codes..
if this a check engine light? then get the codes read to determine the real problem...
remember, more details you put in here are better..
Best regards

Is there a way to reset computer for check engine


2 ways. Go to auto zone & get free scan to get DTC codes and have them erase. Or, disconnect your battery for an hour. It may run rough for 10 miles as it relearns strategy, but codes should be gone.

May come back if issue still there. Get codes & report back or Google the codes,

My check engine light is on and I'm getting codes po411,and p0000


P0411 Secondary Air Injection System Incorrect Flow Detected

I've never come across a P0000 code before, so I have no idea what that signifies. It may be a Ford indication that the P0411 is the only code, as if it is placed at the end of any "list" of codes in the ECU so that you know that you've seen every code currently failing.

Secondary air injection failures can indicate a failure of a secondary air pump, or could be as simple as a vacuum leak. Take some time under the hood and inspect all the vacuum lines - see if any are hanging free or unplugged, cracked, split, or broken. That can lead to failures such as what you're seeing.
