My check engine, service engine, and now a yellow arrow flashes?

Hi,
The service will be due at a certain mileage OR a certain date, whichever comes FIRST.
So if the service book says it should have an 80,000 mile service, that has come first, before the calendar schedule.
It's a yellow warning light, which is a 'first-stage' light. A red light is a problem, a yellow one is just a reminder/warning.!
It's safe to drive it, but get it in for it's service as soon as you can as its now over the scheduled service period.
Best of luck.

If it is the check engine light, Yellow light that looks like a engine, or may say "Check engine", Yes, it is safe to drive until you can get it checked. As long as the vehicle is driving normal. If the light starts flashing, DO NOT DRIVE it. A flashing check engine light means a misfire and could cause a fire due to raw fuel going down the exhaust into the cat converters.

Check engine light comes on and off, these are indication that there is some error code stored in your vehicles ECM. The engine module computer needs to be scanned. These will give the code and as per the error code the further problem can be detected and confirmed. The engine light indicator blinks or remains steady on dash when engine computer noticed any problem with any engine electrically operated components.

For more help, I suggest you to refer the help links provided below. These will let you know more about which areas to look, check, when there is engine light coming up on dash panel.

READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

Why Is My Check Engine Light Flashing? Location

1. The check-engine light may be a graphic of an engine or similar icon, or it may contain the words "check engine" or "service engine." In some vehicles, a red check-engine light means the car needs absolute immediate attention while a yellow check-engine light means you need to make an appointment soon. Either way, you should know the location of the light and periodically glance at it to ensure its status. The light is used to indicate power train problems that are associated with your vehicle's emissions system. (The power train is the engine, transmission and other power parts of your vehicle.)

Flashing Light

1. Typically, a flashing light is more serious than a solid check-engine light. The flashing light is meant to alert you that you may have a misfire in your engine that will cause catalytic converter damage if you leave the problem unresolved. Replacing a catalytic converter can be costly, so have the engine checked as soon as possible by a certified mechanic.

Cause

1. A flashing check-engine light generally indicates that there is a failure in the emission control system. The emission control system contains an array of sensors that work to reduce the amount of pollution released into the air. An oxygen sensor reads the air and fuel mixture and lights up when it is out of range. The acceptable range is between 50 mill volts and 800 mV. If the check-engine light is flashing, you should visit your mechanic or dealer as soon as possible.

Loose Gas Cap

1. A gas cap that isn't twisted on tight enough may cause the check engine light to illuminate, but it won't flash. Try tightening the gas cap and watch the light. In many cases, it will turn off because the problem has been corrected. If the light stays on for more than a day or two, have your mechanic run an on-board diagnostic (OBD) to see if there is a code in the system indicating a serious problem. Your mechanic can reset the light to off if the problem was a loose gas cap.

Spark Plug Wires

1. As spark plug wires age, they can become brittle and crack, causing an electrical misfire. Your check engine light might turn on and stay lit. If this happens, go home as soon as possible, turn off your engine, and inspect the wires. If the wires are brittle and cracked, you need to replace them. If your check engine light stays on after the wires are replaced, have your mechanic run an OBD.

as long as the light is not flashing, you should be good to go. you can also have a parts store scan the system. most parts store will do this at no cost. doing this would make sure nothing serious is going on.

this indicates an automatic gearbox problem associated with the winter mode switch
does your car drive ok or are you stuck in ultra low gear with a max speed of about 10mph??

A yellow light containing an exclamation mark surrounded by a triangle, all surrounded by a curved arrow is the Automatic Stability Control warning light (ASC + Traction Control). If the light just flashes momentarily whilst driving it means that you have driven in a way that has triggered the ASC system to activate and protect you. If the light is on all the time it can mean that you have switched the system off. The switch for the ASC is one of the row of chrome switches just under the airconditioning controls. If you operate the switch and the light stays on, you have a faulty ASC system. OK to drive the car but be aware that the stability control will not save you from a skid. Have it looked at if you can't get the light to stay off.

Normal operation: Light on when you turn on the ignition, should go out after engine starts. Light flashes if you are driving hard on a slippery surface and the system is acting to stabilise the car.

Faulty: Light on all the time measn either you have turned the system off or there is a fault.

Yep 20 seconds on a machine turning 650 rpms is low on oil wil destroy the bearings in the pistons and crankshaft. Mechanics refer to the red check engine light as the idot light, because by that time it's to late the car ran low on oil and damaged the engine.Try putting some SPT oil treatment in and see if it will fix it temporally otherwise you may be looking for a engine overhaul. If the yellow check engine light is flashings you may have burned the rings up on the pistons and it is now burning oil, or more oil causeing it to throw a code for the 02 sensor. Good luck

The yellow arrow up light is telling you, you have a fault with the ride height control system usually a bad ride height sensor on the back axle
