Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

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).

'98 Pontiac Grand Prix SE PO742 torque converter clutch solenoid circuit stuck on Trac off light and service engine soon light stay on


When the PCM detects 3 occurrences of TCC slip between -20 and +50 RPM for 5 seconds, indicating the TCC is applied, when commanded OFF, then DTC P0742 sets. DTC P0742 is a type B DTC.
The PCM energizes the Torque Converter Clutch Solenoid Valve Assembly (TCC Sol. Valve Assy.) by creating a ground path on circuit 422. When grounded (energized), the valve stops converter signal oil from exhausting. This causes converter signal oil pressure to increase and move the TCC apply valve. The TCC Sol. Valve Assy. de-energizes when the PCM no longer provides a ground path. When de-energized, the valve will exhaust fluid and release the TCC

?€¢
Check for PRNDL DTC P0705. DTC P0705 affects transmission operation. This may set DTC P0742 falsely.


?€¢
Inspect the transmission fluid for debris.

Install the Scan Tool .
With the engine OFF, turn the ignition switch to the RUN position.
Important: Before clearing the DTCs, use the scan tool in order to record the Freeze Frame and Failure Records for reference. The Clear Info function will erase the data. Record the DTC Freeze Frame and Failure Records, then clear the DTC.
Start and run the vehicle.
Select TCC Slip Speed on the scan tool.
With the transmission in D4, drive the vehicle through the 1-2 upshift.
In second gear is the TCC Slip Speed within the range specified?
-20 to +50 RPM
Go to Step 3

Inspect for the following conditions:
The TCC apply valve stuck ON because of sediment or damage.
The TCC Sol. Valve Assy. stuck ON because of sediment or damage. Refer to Control Valve Body Assembly Inspection, in Unit Repair.

In order to verify your repair, perform the following procedure:
Using the scan tool, clear DTCs.
Operate the vehicle under the following conditions:
• The gear range is D2, D3 or D4.
• The commanded gear is not 1st.
• The engine speed is greater than 500 RPM for 5 seconds.
• Not in fuel shut off.
• The engine torque is 95-270 N·m (70-200 lb ft).
• The throttle position is 14-50%.
• The PCM commands the TCC OFF.
• The TCC slip speed is 150-2000 RPM for 5 seconds.
• The engine speed is 800-4000 RPM.
• The vehicle speed is 32-112 km/h (20-70 mph).
• The speed ratio is 0.65-1.18.

Have ford s-max with dtc code F00616 what does if mean?


It is a common misconception that the instrument cluster self test gives DTC's for the engine management system, it provides cluster related DTC's on test 10 of the cluster self test, DTC should be displayed above the code, these will be displayed at 1 second intervals, once you press OK again the cluster will scroll to the next test, the format of the codes shown in the cluster is designed for Ford engineering and can only be translated into usable codes by Ford IDS.

The only way to find out why the engine management light is on is to have a scan of the engine management control module carried out using an appropriate code reader, this will give you the standard EOBD codes for example a catalyst efficiency code would show P0420. If you want to do this on a DIY basis then cheap code readers are available on the internet for around $75.00, these code readers also reset the light after the fault has been fixed. if this was helpful please leave me good feedback

2003 Hyundai Elantra can the car fail inspection if your check engine light came on a few times in the last month and 1/2. The light didn't stay on long though Will spark plugs making a backfiring noise...


Until you verify which codes occured, your guess is as good as mine. Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

Trouble code P0325 and P1444


Nissan code:
P1444 Canister Purge Volume Control Solenoid Valve

Generic OBD II code:
DTC Codes - P0300-P0399 – Ignition System or Misfire
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)

I hopes this helps you.
Replace or fix these two items should do the trick.
