New coolant fan and new control module but coolant fan does not work on my 2002 ford escort zx2

The picture is for a zetec. Let me know if wrong diagram?

Did you check the front floor board,heater core could be leaking?

You need to have a repair shop diagnose the problem

Automobiles: 2000 Ford Escort ZX2 4-cylinder 2.0L MFI DOHC

NOTE
The "left" side of the engine is the driver's side.

The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").

The ECT sensor is mounted in the following locations (small Ford engines):

1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine

2.0L Zetec Engine

(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.




Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.

To install:

NOTE
Coat the ECT sensor O-ring with clean coolant prior to installation.

(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.

could be the fan motor or the temp switch connect the fan to the batt directly to test the motor if that works then go to the parts store and ask for the temp switch

make sure coolant level is normal if its full you may have a thermostat thats come apart sounds like your low on coolant though

The cooling fan relay is part of the CCRM (constant control relay module) and it is located under the air filter box. This is listed as non-serviceable but if you can solder, you can take the box apart and get a new relay from Radio Shack and install it yourself.

see diagram on hood or fan guard

This CODE is Indicating that ENGINE COOLANT TEMP is NOT Reaching TEMP HOT Enough to >CLOSE LOOP < This is when ECM takes over ALL ELECTRONIC CONTROLS, . It Basicly Points at A Coolant Temp Sensor that is Faulty or Thermostat that is RATED too LOW. Engine Must Reach 200 - 220 degrees

Yes, All the years of the ZX2 utilize the same engine. 1998-2003 are all the same except for ECU programing and the MAF wiring. You should not have a problem.
