Customer Question

Does the 2001-2004 ford escape 3.0L carry 1cam & 1 crank sensor...?

Expert:  A. Penland replied 8 months ago.

The 2001-2004 3.0L Duratec Escapes have one crank sensor and one cam sensor.

The crankshaft position sensor is mounted on the front of the engine by the crankshaft pulley and belt.

The camshaft position sensor is mounted on the front timing cover in front of the front cylinder head by the radiator.

What is the sensor in the back of the engine an what is the importance of it ?
Expert:  A. Penland replied 8 months ago.

Taking the picture now hold on

I'll wait for the picture. I am not set up for phone calls at this time.

This sensor is in the back of the engine ? The wires are red an white
Expert:  A. Penland replied 8 months ago.

That is a knock sensor.

Customer: replied 8 months ago.
What exactly is the importance of it ?
Expert:  A. Penland replied 8 months ago.

The knock sensor is a tuned accelerometer on the engine which converts engine vibration to an electrical signal. The PCM (Engine Computer) uses this signal to determine the presence of engine knock and to retard spark timing.

Customer: replied 8 months ago.
Can the engine run without that sensor ?
Expert:  A. Penland replied 8 months ago.

Yes, but it can possibly set a check engine light.

Are you sure your Escape is a 2001-2004 V6?
I do not recall one on those years of Escapes.

Customer: replied 8 months ago.
does the 2005 engine have the knock sensor?
Expert:  A. Penland replied 8 months ago.

I had to do a little digging. Ford only used the Knock Senor on the 2001-2003 Escape 3.0L V6. Not the 2004.

Customer: replied 8 months ago.
would the 2003 engine still work with the 2004 model ?
Expert:  A. Penland replied 8 months ago.

The basic engine is the same, just the sensors and the wiring harnesses are different. Are you looking to put a 2003 3.0L into a 2004 Escape?

Customer: replied 8 months ago.
I recently ordered a 2004 Ford Escape 3.0L from AutoParts local. From speaking with you I now see that they sent me the wrong year engine. I am trying to avoid having to re ship the engine back to the seller. I had a mechanic put the engine in a 2004 Ford Escape an the vehicle is just rolling over an wont start.
Expert:  A. Penland replied 8 months ago.

The base engine, the cylinder heads and engine block are basically the same. But you will need to use the sensors and wiring harness from the old engine and put them on the new engine. If all this was done and the engine does not start, just spins over, then either something is not connected properly, or the base engine is bad and he should do a manual compression test on each cylinder which should be about 175 PSI per cylinder.

Customer: replied 8 months ago.
Could you call me...?
Customer: replied 8 months ago.
Could the 2003 wiring an harness work in a 2004 body ?
Expert:  A. Penland replied 8 months ago.

No. You will have to use the 2004 harness. They are different year to year. Years ago, you could do that. But not with the newer vehicle and all the modules and sensors.
