Section 8 Condenser Fan Motor and Condenser AssemblyOn-board Inspection1. check condenser assembly
(1) if the radiator in the condenser is dirty, wash it with clean water and dry it with compressed air.
(2) if the radiator in the condenser is distorted, use the proper tool to correct it.
2. check the condenser for coolant leakage.
(1) use the leakage tester to check the connection area of the pipeline for leakage.
(2) If there is leakage, check the connector set bolt for tightening condition.Component Viewcondenser fan upper cushion

Overhaul1. Drain coolant (refer to Coolant for details).
2. Remove condenser fan motor assembly
(1) Disconnect condenser fan motor wire harness connector.
(2) Unscrew 1 bolt, remove condenser fan motor assembly.
3. Disconnect the liquid tube
(1) Remove the bolt, disconnect the liquid tube from the condenser.
(2) Remove the Oring from the liquid tube.
4. Disconnect the high and low pressure pipe assembly
(1) Remove the bolt, disconnect the high and low pressure tube
assembly from the condenser.
(2) Remove the Oring from the high and low pressure tube
assembly.
Notice: Use vinyl tape seal all the interfaces of the disconnected
parts to avoid entry of water and foreign objects.
5. Remove engine hood lock assembly
(1) remove the bolt, remove engine hood lock assemblyAir Conditioning System -Condenser Fan Motor and Condenser Assembly5-97

Fault symptom Possible cause
Poor speedup etc Man made fault1 2 3Throttle position sensorFault symptom Possible cause
Difficult to start Man made fault Repair precautions: pay attention to mounting position.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 1 #, 2 # pin respectively, its resistance
value at room temperature is 2k ohm±20 %. Connect two meter pens
with 1 #, 3# pin respectively, rotate throttle, its resistance value shows
linear change with opening of throttle, while situation is reverse for
2 #, 3# pin.
Note: when observe change of resistance value, pay attention to observe whether has large leap.
3. Coolant temperature sensor
(1) This sensor is a negative temperature coefficient (NTC) thermistor, its resistance value decreases with
increase of temperature, but not a linear relationship. This thermistor is installed in a copper heat conducting sleeve.Engine EFI System-Engine EFI System5-121should drop.
Pressure sensor part: (connect joint), turn digital multimeter to DC voltage position, black meter pen is earthed,
red meter pen is connected with 3#, 4# pin respectively. In condition of idle speed, 3# pin should have reference
voltage of 5 V, 4 # pin voltage should be about 1. 3 V (specific value is related with vehicle type); in no-load
condition, open the throttle slowly, change of voltage of 4 # pin is not large; open the throttle quickly, voltage of
4 # pin may reach about 4V in no time (specific value is related with vehicle type), then it drops down to about
1. 5 V.
2. Throttle position sensor
(1) This sensor is actually corner potentiometer with linear output characteristic. Potentiometer tumbler is
mounted coaxially with throttle, when throttle rotates, it drives potentiometer tumbler to slide to certain position,
potentiometer outputs voltage signal proportional to throttle position. Mounting torque: 20 N.m(Max)
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with sensor pins respectively,rated resistance at 20°C is 2.5 k ohm± 5%. Simulation method may also be used for measurement, specificprocedure is to put sensor work area into boiled water (pay attention to soak for sufficient time), observe changeof sensor resistance, now resistance should drop down to 300 ohm-400 ohm (specific value subjects to temperatureof boiled water).

procedure: use engine data K-line (namely 9 # terminal of diagnostic interface) earth twice, earthing time is more
than 2. 5 s at each time.
