Check Engine Light
I have a check engine light on and scanned it myself. It turned out the fuel was too lean in bank 1. In addition every time I fuel up where it's more than half a tank the light goes away but when it has less than half it comes on again. I also have another question, My truck still shakes starting while acceleration at 50 mph and goes away at 60 mph. I asked earlier abouand did what I was told but the problem is still there.
My car has 170300 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Typically if you have a warning light that comes on as you’ve indicated above, it could be related to an EVAP system component or sensor failure. The EVAP solenoid for example tends to trigger an error code when the fuel tank has less than 50% capacity. However, it’s quite possible that the fuel level is not related at all. Most of the time, a bank 1 failure is due to an O2 sensor or O2 sensor harness that is faulty. In order to correctly diagnose this problem, it’s probably a good idea to have a professional mobile mechanic come to your location and complete a check engine light inspection.

Other common reasons for a Check Engine Light are dirty mass airflow sensor, a malfunction with the fuel injection system, faulty emissions control part, damaged oxygen sensor, faulty head gasket, or defective spark plugs to name a few.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
Dodge Check Engine Light Flashing
Other generally common reasons for a Check Engine Light are dirty mass airflow sensor, faulty emissions control part, a malfunction with the fuel injection system, damaged oxygen sensor, faulty head gasket, or faulty spark plugs to name a few.
Flashing Check Engine Light: If your check engine light is flashing, stop driving your Ram 1500 and have it towed to your nearest mechanic – a blinking check engine light means you probably have a very serious problem with your car and you risk ruining your engine by driving it.
It`s okay to drive the car if the check engine light is steady. But only if the vehicle`s essential systems such as brakes and lights are operational. Keep a close eye on your car`s dashboard warning lights, including the coolant temperature and oil pressure.
A steady check engine light indicates a non-emergency issue, such as a loose gas cap. Flashing check engine lights warn of severe situations requiring immediate attention. Standardized diagnostic codes help identify the trouble.
You can judge how serious an issue is by looking at the warning light. The check engine light can show up in two ways: Solid yellow/amber light: Indicates a less urgent issue. Flashing light or red: Indicates a severe problem that needs immediate attention.
No.
Sometimes, the check engine light comes on to let you know that there`s a problem with the car`s internal diagnostic mechanism. That means the system could be “finding” a problem that doesn`t exist, or it could be that loose wire systems are creating a false positive in the system.
One of the most common reasons your check engine light may come on is that your oxygen sensor is failing. Your local auto repair shop in Western Washington can replace it for you quickly, which will restore your vehicle`s ability to measure unburned oxygen in its exhaust system.
These problems can range from faults within the electrical system, the engine, fluid levels or to problems within the car`s emissions system. The problem can even be as simple as forgetting to tighten your gas cap – in fact, this is the most common reason why check engine lights appear in the first place.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.
When your check engine light begins flashing, it is most often caused by a charging system misfire. The fuel, oxygen, and spark in your vehicle must operate in a specific order to power it properly. Unfortunately, if one of these three cylinders malfunctions, the entire system will suffer.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.
Do not delay. Continuing to drive with the check engine light on can potentially cause serious damage and costlier repairs. Moreover, you will likely see diminished fuel efficiency and performance of your vehicle. You should bring your vehicle to a qualified service center as soon as possible.

ANSWER : It is possible that you could be having an issue with your powertrain control module. This is somewhat of a common problem on many GM vehicles.

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.

p0011 code,check engine light one, changed bank 1 vvt solenoid and check engine light still on?
ANSWER : The P0011 code is typically caused by oil issues with the car. I would particularly make sure the engine oil level is not low. The VVT solenoid relies on proper oil levels to do their job. If they don’t have enough oil, they won’t work. You can have a mobile technician from YourMechanic visit your home or office to inspect the Check Engine Light for you. If you follow through with a repair with us you will be reimbursed for the cost of inspection.

Traction light/reduced engine power and check engine light coming on
ANSWER : Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.

Check Engine Light comes on after starting pickup
ANSWER : Hello there, thank you for asking about your 1992 Isuzu Pickup. A professional will have the correct equipment to read OBD1 codes. Retrieving the diagnostic trouble code(s) is the first place to start when diagnosing your vehicle. Increasing RPMs changes engine load, which can in turn affect many different sensors and components, causing the Check Engine Light to illuminate. The only way to narrow down the options and find the culprit is through in person diagnosis with an OEM compatible scan tool. A certified technician from YourMechanic can retrieve the OBD codes at your home or office.

ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on.
