SOURCE: Check Engine Light is On

You did what thousands of people do they get a code and jump straight to replace a part no testing just guessing. code 43 is a fuel system problem code sure enough you absolutely need proffessional diagnostic help with this one you cannot go on another hondas code 43 because you can have two hondas exact same symptoms and even the color of the interior and have two completely different problems I realize it costs money to diagnose the problem but which is cheaper to pay diagnostic and only change the one bad thing or replace part after part then take it to be diagnosed and have them change one part?
Cmon Please do the right thing for your wallet honda is not a car for anyone but a professional to diagnose and fix.

SOURCE: check engine light comes on upon start up

Yes the shops technician got it right. as per the error code which you mentioned.These 2 codes are usually caused by a faulty crankshaft sensor (P0321) & possibly an ignition module (P1361). When replacing these parts part attention to the female electrical terminals in each connection. They will sometimes "spread" & cause an intermitten open circuit. Check each female electrical terminal with an opposing male terminal. There should be a small amount of "drag" when connecting the two of them. Thanks.Helpmech.

SOURCE: I have a 2003 Envoy- GMC. Why does the reduce engine speed light come on

you need to scan you vehicles ECM, there is a trouble code stored there. depending on where you live most parts stores( such as a shucks/orielleys) will have a scan tool they will let you use if the vehicle is in thier parking lot. this should diagnose the issue, provided the battery hasnt been disconnected since then.

The lights will illuminate for two seconds when the ignition is turned to the on position
The lights will turn on and then off when the engine is started
The lights may come on and stay lit after the engine has started then turns off when the vehicle reaches about 25 mph / 40 kph
The lights may come on during driving but then turn immediately off. - - However, do not hesitate having the computer codes and system checked by your Subaru specialist. Good luck.

I change the battery in my 2007 equinoxLT AWD and it will not start the shift selector light does not turn red when i shift to drive what is the problem?


You probably lost the programming for the anti-theft. Many cars require you to keep power through the system to keep this from happening when a person changes a battery. Try the following: I found this online, worth a shot. This is to reset the Passlock.
Important: Do not remove the key from the ignition during this procedure. If the key is removed, the procedure will have to be performed from the beginning.
  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON. The vehicle will not start.
  3. Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF.
  4. Turn OFF the ignition, and wait 5 seconds.
  5. Repeat steps 1-4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to RUN. Important: The vehicle learns the Passlock Sensor Data Code and/or password, the next ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle.
  6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.
  7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

Engine light come on after a min


Hi there:
The four most common Check Engine Light scenarios and what to do:

* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Pay attention at the self-read Jeep codes procedure, note the code numbers there and send it us for additional details:
- put key in ignition
- push and hold the odometer/trip mileage button (the little black one that comes out of the gauge cluster)
- turn the key to the "ON" position (where all the electronics turn on / do not start the Jeep, just turn it to "ON" three times...
ON / OFF / ON / OFF / ON
- Check odometer and note the Pxxxx codes showed there.

Additionally, if you have some Autozone or Autoshop early, they could make this job for free (sometimes) with OBD Scanner Reader Tool.

Hope this helps

Does the light ever come on while you are driving the vehicle? It is possible that the vehicle does not trigger the code on the key cycle when vehicle is connected to the OBDII scan tool (a cycle is the time from when a vehicle is started to the time the vehicle is turned off) you should however most of the time be able to check a vehicles trouble code history to see what may be turning the light on
