High-Speed Fan

Enable the High-Speed cooling
fan

ON/OFF

Note

Carry out this test only when the engine
coolant temperature is below 100°C
(212 ºF) and Air-Conditioning is not switched
on.

This function controls the High-Speed cooling fan
relay. When the instruction is received, the cooling
fan will be on at high speed for 5 s.

Air-Conditioning Clutch

Enable the Air-Conditioning
compressor clutch.

ON/OFF

Note

Carry out this test only when the ignition
switch is at "ON" position and the engine is
not running.

This function controls Air-Conditioning
compressor relay. When the instruction is "ON",
the Air-Conditioning compressor relay will be on
or off in 3-5 s.

2.12.7.11 Crankshaft Position Sensor (CKP) Learn

Note

After crankshaft position sensor replacement, ECM replacement or engine replacement, the crankshaft position sensor
adaptive learn must be carried out. Otherwise the fault warning lamp will be always on, while ECM will record "P1336
58-tooth gear tolerance does not learn "DTC code.

Before the gear learn, the following conditions must be met:

1. Make sure the engine coolant temperature is above 60°C (140 ºF)

2. Air-Conditioning switch is not turned on.

3. 10 s after start the engine.

Carry out the following steps when the above conditions are met:

Step 1

Connect scan tool.

(a)

Connect scan tool to the datalink connector.

(b)

Turn the ignition switch to "ON" position.

(c)

Start and run the engine at idle speed to warm up the engine
for at least 5 min.

(d)

Select the "engine" / gear to learn.

Next

Step 2

Carefully read the instructions attached to scan tool and press confirm key.

Next

Step 3

Enter the learning interface,press start button.

Next

Step 4

Press the acceleration pedal to 80% of the full travel and keep the pedal position.

Next

Step 5

Make the engine speed jumping back and forth between 1,300 rpm and 4,500 rpm 3-5 cycles, maintain the
engine speed at above 4,000 rpm.

Next

Step 6

Release the acceleration pedal, Turn the ignition switch to "OFF" position.

2. Throttle Position Sensor Technical Specifications

As one of the system security measures, the system consists of dual output throttle position sensors. One throttle position sensor
output voltage signal increases as the throttle body opening increases, while the other throttle position sensor output voltage signal
decreases as the throttle body opening increases.

Resistance Between Terminals A and D: 1.9 ± 0.9 kΩ

Note

When test the above TPS sensor output signals, use an oscilloscope. the output waveform of the circuit should be
smooth and without other waveforms. If the throttle body rotates to an angle and the output signal drops to zero or
drops rapidly, replace the ETC. ETC is an assembly. Do not disassemble it to repair.

2.12.7.13 Acceleration Pedal Position Sensor (APP) Check

As one of the system security measures, acceleration pedal position sensor is designed to have dual outputs. Two sensors output
voltage signals increase as the acceleration pedal position increases.
