Low Throttle Signal

- Causes

• The throttle valve position

sensor signal is stuck low.

- Check pin for the followings:

• Throttle valve #1:

sensor (Power) . . . ECU #A20

• Throttle valve #2:

sensor (Signal) . . .. ECU #A22

• Throttle valve #3:

sensor (GND) . . . . ECU #A81

• Throttle valve #4:

valve (Positive) . . .. ECU #A75

• Throttle valve #5:

valve (Positive) . . .. ECU #A77

- Sensor & Motor SPEC

• Motor

* Power: 12V

* Max. current : 6.8A (Normal: 3.6

~ 0.2)

* Motor resistance: 4.3

Ω

• Sensor

* Power: 5V

- Actions

• Check the throttle valve and sen-

sor wiring harnesses. (The sig-
nal output of throttle valve is be-
low than 0.24 V.)

• Visually check the unit and re-

place if necessary.

P213D

High Throttle Signal

- Causes

• The throttle valve position

sensor signal is stuck high.

- Check pin (refer to P213C).

- Sensor specification: Refer to P213C.

- Actions

• Check the throttle valve and

sensor wiring harnesses.

• Visually check the unit and

replace if necessary.

#3 Glow Plug Short
(Battery)

- NGK glow module (AQGS: Ad-

vanced Quick Glowing System)

- It is detected by AQGS which then sends

the message to ECU through CAN.

- The electrical problem is occurred in

AQGS.

- Diagnosis criteria in AQGS

• Plug short: voltage > 6V, current

= 0A

• Plug short (GND): voltage = 0V

• Plug short (battery): voltage =

Battery voltage

• FET defective, FET short (GND):

voltage = 0V, current = 0A

• Abnormal input voltage: 6V <

input voltage < 16V

• Abnormal communication:

Communication error for over 1
sec., abnormal data

- Actions

• Check glow plug for defect

(measure the resistance of unit).

• Check the connector and wiring

harnesses.

• Visually check the unit.

• Replace the unit if necessary.

• Check the CAN line.

• Check the IG1 voltage.

• Check the battery voltage.
