FORD ESCAPE EMISSION CONTROL WARNING LIGHT PROBLEM: I have a Ford Escape XLT, 6 cylinder, 2002 model, and the above warning light comes on, on the dash. The problem is, that it only comes on after the car has been started, but once this light is on, it says on for a long period of time. I have been advised by a mechanic that it could be the Oxygen Sensors, so I have had these two replaced, but this light still comes on. Do you agree with the opinion of this mechanic, or do you think it could be something else? The car has done over 200,000 kms. Thanks

It is plugged into the intake manifold. There is an emissions sticker under the hood that shows the vacuum hose routing. The MAP sensor should be shown on that.

check for correct oil level in the sump first
this indicates insufficient oil level and the surge of the oil when stopping is allowing air into the pump and putting the light on

I believe the fluid/brake light is only intended to indicate the parking brake is on or the master cylinder reservoir is low . ?????

Wrong !!!!!! problem's with ABS can also turn on that light as well ! Take it a have codes checked .

Your alternator is failing

P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.

look at the fuel cap, make sure the rubber is good ans not cracked and has no dirt build up on it, if it does clean it good. While you are there check the filler neck where the cap fits make sure it is smooth and not rusty, if it is, clean it good. the vehicle will randomly run a evap test checking for a vacuum build up in the tank if it does not sense the vacuum it will put on the light and it will stay on until it runs the test and the vehicle passes the test. That it the reason there are signs at the gas station that say shut off your vehicle when fueling. make sure the cap is on properly and on tight before leaving.

Hello! No, I disagree...The warning light is the Check Engine Light (CEL)...When it comes on it is the computer telling you that a trouble code/codes have been stored...There is a lengthy list of codes...Take the vehicle to an auto parts store and have them run a scan (done for free) to find the code that is setting the warning light...Oxygen sensors as well as many, many other sensors will set a trouble code if faulty...There are 4 Oxygen sensors not 2 on your vehicle...In many instances the O2 sensor fault is an effect not a cause...Lets find out what the trouble code is before jumping to an expensive conclusion...Send a comment when you have the code...Guru...saailer

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

Have the car scanned and find out what code has come up...It may be something else...

Zeevert was right about all but one thing. Cylinder two is the rear middle cylinder on a V6 or the second one from the passenger side on a 4 cylinder.

he is pushing the button a second time which is unnecessary.
it will cause damage to the lock actuators. yours will do it if you push the lock button a second time, but i do not recommend as stated above.
