- Causes (Idle range MDP learning)

• The MDP is not learned again
until driving over 50,000 km after
the MDP is learned.

- Conditions for MDP learning (Idle)

• Leaning twice for each cylinder
(attempt every 5 sec.)

• Initial MDP learning: coolant
temperature > 60°C

• Fuel temperature: 0 ~ 80°C

• Vehicle speed: Idle.

• The tachometer's needle
vibrates while learning idle MDP.

• Replace ECU after learning.

- Causes

• It occurs twice for each cylilnder
if MDP is not learned again until
driving over 50,000 km after the
MDP is learned.

- Actions

• Check knock sensor and wiring.

• Check injector specification.

• Check C3I/C2I.

- MDP learning value is decreased
due to aged injector #1.

- MDP learning value is decreased
due to aged injector #2.

- MDP learning value is decreased
due to aged injector #3.

- MDP learning value is decreased
due to aged injector #4.

Help

- The signal / noise ratio is too low
about accelerometer # 1.

- Check the accelerometer wiring
harness and tightening torque.

• Tightening torque: 20 ± 5 Nm

- Check the ECU wiring harness for
open and short.

• ECU pin #45 and #46

- If the trouble still exists even after
replacing the accelerometer,
replace the ECU.

- Refer to P0372.

- Air gap of crank angle sensor is
abnormal.

- Check the sensor wiring harness
for ECU pin #90 and #82 (open,
short, poor contact).

- Check the resistance of crank angle
sensor: 1090 Ω ± 15 %.

- Measure the air gap: 0.3 ~ 1.3 mm

• 1.3 mm of air gap: outputs 1.0 V
at 40 rpm

• 0.3 mm of air gap: outputs 150 V
at 7000 rpm

- Check the teeth condition.

• Drive plate (A/T), DMF (M/T)

- Replace the ECU if required.

- Not synchronized with Crank angle
signal.

- Check the source voltage of cam posi­tion sensor (specified value: 4.5 ~ 12 V).

- Check the sensor wiring harness
for ECU pin #103 and #104 (open,
short, poor contact).

- Check the cam position sensor.

- Measure the air gap: 0.2 ~ 1.8 mm

- Replace the ECU if required.

- No cam recognition signal (missing
events).

- Check the source voltage of cam
position sensor (ECU pin #111)
(specified value: 4.5 ~ 12 V).

- Check the sensor wiring harness
for ECU pin #103 and #104 (open,
short, poor contact).

- Check the cam position sensor.

- Measure the air gap: 0.2 ~ 1.8 mm

- Replace the ECU if required.

- Check the teeth condition.

• Drive plate (A/T), DMF (M/T)

- Replace the ECU if required.

- When the EGR emission is more
than specified value.

• The EGR controller circuit is
open or short to ground.

• The EGR controller is short to battery.

- Check the EGR actuator wiring harness.

- Check the supply voltage to EGR
solenoid valve.

- Check if the EGR valve is stuck.

- Check the resistance of EGR valve:

15.4 Ω.

- Check the ECU wiring harness.

• Check the ECU pin #96 for open
and short.

- When the EGR emission is more
than specified value.

• The EGR controller circuit is
open or short to ground.

• The EGR controller is short to battery.

- Check the EGR actuator wiring harness.
