1.

Possible DTC :P0335

2.

Actual value for evaluation : Engine warm ＞ 80°C, aircondition off

A.

Required idling speed

SM : 750 ± 40 rpm (M/T, A/T)

FO : 780 ± 40 rpm (M/T, A/T)

XD : 750 ± 40 rpm (M/T, A/T)

o CC-CODE

B.

Substitute reaction is performed anyhow.

C.

NOTE : When excessive engine oil is filled up, for instance 2 times of normal amount, engine can be run more than 6000rpm (i.e. dieseling) in this case error can be memorized but this should be neglected.

(1)

C004 (Plausibility error)

A.

This error is reduntant to DTC340 can occur only if DTC340 CC-Code C004 occurred.

B.

Measure the signal rate between present engine speed(k) and previous engine speed(k-1). If the rate is out of the standard, it is detected as an error.

C.

Possible causes of trouble:

a) Contact resistance

b) CKP defective

c) Metal abrasion or dirt at sensor

d) Incorrect installation position or sensor loose

e) Wheel - CKP sensor

3.

Measure the resistance of sensor at the detached plug pin1 to pin 2

650 ~ 1000&amp;Omega; at 20°

4.

Attach the plug.

5.

Record the signal profile from pin1 to GND. Engine idling.

Using oscillocope :

A.

CMP signal

B.

CKP signal

Wiring check:

ECU

CKP

Pin 69

Pin 100

Pin 1

Pin 2

Pin 3

6.

If wiring is OK and signal profile doesn't correspond to set value (Min. 1.65V), check the sensor for dirt (possibly abrasion or some metallic parts), proper installation position and tight fit.

Measure the gap between sensor wheel and sensor:

1 ± 0.5 mm

Gap cannot be adjusted. Check the sensor wheel for damage.
