Land rover over heating and check engine light flashing
It started with my check engine light flashing. Then my car started to shake, very lightly. The heater was blowing out cool air, no matter what. Finally, my car over heated. I would pull over and shut of the engine for 2 seconds, and the needle would go from at the red section, back to the middle. Haven't noticed any major leaks, though I think I may need an oil change. We tried to open the coolant reservoir, but it was hissing and bubble when we started to unscrew the cap, so we just didn't mess with it. What does it sound like the problem is? Helppp.
My car has 134000 miles.
Experienced mechanics share their insights in answering this question :
This is a result of your engine overheating which may be caused by a faulty thermostat. When this is stuck closed, this does not allow the coolant to flow through the motor properly. This may also cause the coolant to not circulate through the heater core which is what causes the heater to blow cold air. As the warm coolant circulates through the heater core, the heater blower motor blows the warm air through the vents inside the cab of the vehicle. When the coolant is not being circulated properly, the blower motor has no way of creating warm air to blow through the vents. I would recommend having an expert from YourMechanic come to your location to diagnose your cooling system.

If the check engine light in your Land Rover Discovery starts flashing, that means that the problem needs prompt attention and your Land Rover should be brought in promptly. A flashing light indicates that the problem is dangerous and if not taken care of promptly may result in good damage to the vehicle.
This may be due to a poor wiring connection, or a failing sensor. P1167 is telling you that the issue is electrical and most likely not a symptom of the vehicle`s engine malfunctioning. At this point, you will want to double check the connection to the sensor and make sure it is clean, dry, and tight.
Hello, as hard as it may be to believe, flushing your cooling system or heater core has absolutely no bearing on the check engine light flashing. The check engine light flashing is due to an engine performance concern that causes cylinder misfire of the engine.
If the check engine light in your Land Rover Range Rover starts flashing, that means that the problem needs sudden attention and your Land Rover should be brought in quickly. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system.
While the check engine light can definitely be indicative of serious problems, the most common cause of the flashing is usually an engine misfire. There are many reasons why an engine misfire might be occurring. To run smoothly, an engine must be receiving the correct amount of power from the cylinders in your vehicle.
A flashing CEL indicates a severe problem, one that requires immediate car repair. In other words, if your check engine light is flashing, pull over and call a tow service. Continuing to drive your car with a flashing CEL can cause irreversible damage to internal components.
Your check engine light is on: If the engine`s computer detects a problem with the coolant temperature sensor, or its circuit, it will turn on the check engine light.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
Key signs to look out for:
Weak or no airflow. Cold air (not warm) coming through the vents when the heater is on. Coolant leakage visible inside the cabin or a damp smell.
If your check engine light is flashing, something is wrong with your engine. You need to pull over and shut it off as soon as it`s safe to do so. The check engine light flashing when accelerating combined with white exhaust appearing and disappearing suggests a sticking fuel injector.
emergency. Warning lights are a suitable means of monitoring the status of your vehicle`s engine. It is only necessary to check your engine when a warning light is flashing.

Check engine light refuses to go off after engine replaced
Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.
Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.
To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
While driving on freeway truck goes into a limp mode, and the check engine light, abs light, parking break light, service brake
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. I would recommend having your vehicle inspected by the dealership to determine if the powertrain control module is functioning properly. If not, a reflash of the powertrain control module may resolve the issue but often times it must be replaced.

2006 Ford Mustang has check engine light on
There are countless potential causes for your illuminated check engine light. The mechanic manually turned off the light, but it came back on because the problem has not been fixed. The first place to start is retrieval of the stored diagnostic trouble codes (DTCs). These codes serve as a starting point for any further diagnostics a mechanic may perform. Codes will be stored anytime the check engine light is on. Since the first mechanic was unable to fix your concern, I recommend giving the professionals at YourMechanic a call. We offer expert check engine light diagnosis and repair.
Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
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?
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.
Check Engine Light comes on after starting pickup
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.
Traction light/reduced engine power and check engine light coming on
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.
