Oxygen Sensor
Some vehicles have (2) and some have (4) O2 sensors.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions.
You will need;
Oxygen Sensor Socket
Anti-Seized
Penetrating Oil
I have even used a small plumbers propane tank and heat it up and it help get them free.
Sometimes it will take 15 minutes or take a few hours it depends on your luck...
I don't have an answer but I have exactly the same problem!!
The sensors go bad and are $188.00 a piece @ the dealer.
Diagnostics
transmission is going out and bad
Do you mean a bad timing chain ? The 2.3 liter four cylinder engine in a 2005 Ford Escape has a timing CHAIN instead of a timing belt
There may be three possible causes of fuel pump hum on a Ford Escape. These are the exhaust leak, wheel bearing, or a bad tire.
it will randomly stall at the stop light
my 2001 ford escape sputters and carries on it doesn't want to run when it is rainy or damp out I have replaced 4 of the six coils cause they were bad so what now????
I have a 2004 and have had to replace transmission, and replace brakes a lot
Your 2001 Ford Escape could be cutting of for a number of reasons including, low on fuel and a bad motor. You should have your truck towed to a garage to have it checked.
A 2001 Ford escape differential leak is usually caused by a bad seal. Replace the differential seal. The new seal should stop the oil leak.
THE no. 1 sensor to affect are the oxygen sensors. They heat up to be able to take proper readings just after the catalytic converters. If they are out of calibration , just not working, or your cats are clogged, they will run in a "looped circuit" and give horrible mileage because of the bad readings. This is a major circuit for fuel/air mixture. You can only imagine ....
