what causes the engine light to come on after having my ford escape service

Ford check engine light will turn on when you lot plow on the ignition under normal operation but should turn off and stay off once you kickoff the engine.

What does information technology mean when the Ford check engine light comes on?

If the bank check engine light in your Ford comes on when driving, it means the On-Board Diagnostic (OBD) system has detected a problem with the engine or emission arrangement. If the check engine light is flashing, it indicates a severe engine misfire which allows unburned fuel to be dumped into the catalytic converter.

Symptoms

Hither are some of the most common symptoms owners notice when their Ford bank check engine lite stays on.

• Ford may idle or run rough
• A subtract in fuel economy
• The engine won't stay running
• Ford loses power or is stuck in gear.
• Hesitates during acceleration
• Powertrain malfunction/Reduced power - this message comes on when a powertrain trouble has been detected.

In some cases, the Ford check engine light comes on, and no other symptoms are noticed.

How to Reset Ford Check Engine Light

The first step in troubleshooting the check engine light is to read the mistake codes with an OBD-Ii scanner.

1. Locate the diagnostics port nether the dashboard of your Ford.
2. Connect your OBD-II scanner to the diagnostics port. Plow on the ignition by pressing the Beginning button without pressing the restriction pedal.
3. Allow the scanner to ability up.
4. Select Engine Module, so press read to call back codes that accept triggered your Ford check engine low-cal. These are the codes that have triggered the check engine calorie-free on your Ford.

5. Once you prepare the problem that triggered the code, come dorsum to the main bill of fare and select Erase Fault Data.

Your Ford bank check engine light on causes vary. Without reading Ford check engine diagnostic trouble codes (DTC), it is difficult to know the problem.

These instructions work on 1996 and newer Ford vehicles, including Ford Mustang, Focus, Fiesta, F-150, Ranger, Explorer, EcoSport, Escape, Fusion, F250, Expedition, Edge, Transit, Taurus, Flex, Shelby GT, C-Max made in the USA. On European models, vehicles must be 2000 or newer.

Common Problems That Trigger Ford Check Engine Light

This is a list of the about common bug that trigger Ford's check engine light to stay on.

• Loose gas cap
• Oxygen sensor
• Spark plus
• Mass airflow sensor
• Catalytic converter
• Vacuum leak

Hundreds of possible causes will turn on the Ford check engine calorie-free. To find out why the check engine low-cal is on in your Ford, read the fault codes.

Let's look at some of the nigh common issues and codes that often cause the check engine light to stay in a Ford vehicle.

Loose Gas Cap

One of the nigh mutual triggers of the bank check engine low-cal on a Ford vehicle is a loose gas cap. If you recently stopped at a gas station, brand certain the gas cap was properly tightened.

In some cases, the O ring in the fuel cap gets damaged. If that's the case, you will need to replace the fuel cap. You can use an OBD-Two scanner or drive the vehicle for a few days for your Ford engine computer to reset the check engine light.

Newer Ford vehicles equipped with Easy Fuel accept no gas cap at all.

Mass Air Flow Sensor

Oftentimes referred to as the MAF sensor, the mass airflow sensor can neglect, triggering the Ford cheque engine light to come on. If your Ford MAF sensor is defective, yous will notice engine hesitation during acceleration and a dramatic fuel economy decrease.

Typical codes are stored in the ECU when the MAF fails P0171 and P0174. Resetting these codes by disconnecting the battery for a few minutes does not gear up the problem. In a few cases, you may fix this problem by using a MAF sensor cleaner.

The recommended set up is to replace your Ford Mass Air Flow Sensor with a new OEM Ford unit. Aftermarket Ford MAF sensors tin sometimes malfunction fifty-fifty when brand new.

Oxygen Sensor

The oxygen sensors (O2) mounted on the catalytic converter can neglect to cause the check engine light to come on, poor engine performance, and a decrease in fuel economy.

One of the most mutual Ford codes related to the oxygen sensor is P0132, caused past an oxygen sensor circuit loftier voltage.

VCTR Solenoid

A common trouble that triggers the check engine low-cal on Ford vehicles, particularly Fusions equipped with the four cylinder engine, is a defective Variable Camshaft Timing solenoid known as VCT solenoid.

A defective VCT solenoid will cause the engine to run rough and trigger the check engine lite simultaneously. The code related to this problem is unremarkably P0012 - "A" Camshaft Position - Timing Over-Retarded (Bank 1). Related codes include P0011, P0010, P0013, P0014.

Ignition Coils

The ignition coils may fail, triggering the Ford check engine low-cal to come on. Mutual symptoms include check engine light on but engine misfire, running rough, and mistake codes ranging from P0300 through P03012.

It is recommended to change the spark plug boots at the same time. If your Ford check engine low-cal stays on after replacing the ignition coils, check the MAF sensor, spark plugs, catalytic converter, and the ECU.

Decision

There are hundreds of possible problems that tin cause Ford check engine light to come on. The most common bug are spark plugs, oxygen sensors, and catalytic converter failure. Instead of guessing what is incorrect, use an OBD-II scanner to read the fault codes.

What does information technology hateful when Ford check engine light flashes?

If the bank check engine or service engine light is flashing, it ways that the OBD-2 system has detected an engine misfire. This is often acquired by a bad spark plug or defective ignition coil but tin exist caused by other bug.

When your Ford bank check engine calorie-free is flashing, fuel is not getting burned in the cylinder just is existing unburned and typically gets burned at the catalytic converter.

Avert driving your Ford if the check engine light is flashing, as this status may crusade unnecessary harm to the engine and the catalytic converter.

Ford Cheque Engine Light Flashing 8 Times

If your Ford check engine low-cal blinks eight times when y'all plow on the ignition, information technology means that it is not set for State Emission Inspection, I/Thousand test. This typically happens if the codes were recently erased with an OBD-Two scanner or the battery was disconnected.

As long as the lights stop blinking after eight flashes, you can go on to drive the vehicle. All systems should be tested within a few driving cycles, and the CEL should no long flash at startup.

Oftentimes Asked Questions

Tin can I reset the check engine light by disconnecting the car battery?

• Aye, disconnecting the battery unremarkably clears the ECU codes. By turning the check engine light off this way, you lot will not fix the problem. If you believe the check engine calorie-free needs to be off, drive the automobile for a few days, and the CEL volition reset itself. The Onboard Diagnostic System in your car continually monitors your vehicle and will plough off the CEL if the problem is solved. If the problem hasn't been resolved, even if you disconnect the battery, the CEL will come support over again, which can exist as soon as you lot restart the machine or up to a few days.

Will my auto pass safety emissions if the check engine light is on or recently reset?

• If the check engine light is on, information technology volition not laissez passer the emission inspection/smog test. If the low-cal was recently reset with an OBD2 scanner or past disconnecting the battery, you demand to drive the auto for a couple of days for the systems to be set up for testing.

Cheque engine calorie-free is on but no codes?

• Information technology could exist because y'all are using an OBD2 scanner that does not support the protocol used in your car. Endeavour a unlike scanner. Also, at that place may be an issue communicating with the ECU due to a damaged wire or ECU malfunction.

Would the check engine lite on cause the motorcar to not start?

• No. The check engine calorie-free is not the reason why the car doesn't start. If the car doesn't beginning, read the codes, and maybe the CEL will give you a code that can help you diagnose the car. Clearing codes will not make your automobile beginning.

Is information technology normal for the cheque engine light to turn on later repair service?

• No, the CEL should not plow on subsequently routine maintenance. If you modified your engine, manual, exhaust, intake, fuel system, or other systems, it could impact the engine and emission control system, causing a check engine or service engine soon light to come on. CEL should non come on if you changed tires or tire size.

Why is my check engine lite on after replacing the battery?

• Drive the automobile for a couple of days and allow the ECU to reset itself. If the CEL remains on, read codes.

Why did my check engine light turn on when the engine overheated?

• The bank check engine light is trying to tell you that in that location is a trouble with your engine. It could be depression coolant, stuck thermostat, transmission non shifting.
