Abnormality Judgment
WARNING: This page is about a different variant/trim than selected.
Judge NG when the malfunction criteria below are completed.
Judgment Value
JUDGMENT VALUE REFERENCE (ABNORMALITY)
| Malfunction Criteria | Threshold Value |
|---|---|
| Engine coolant temperature | < 20°C (68°F) |
| Timer for diagnosis after engine starting | >/= Timer judgment value after engine starting |
Timer for diagnosis after engine starting
- Timer stop at fuel cut mode.
- During the driving conditions (except a) above), timer count up by 64 milliseconds + TWCNT milliseconds (at every 64 milliseconds). Where, TWCNT is determined as follows, TWCNT = 0 (at idle switch ON),
Refer to the following table for TWCNT with idle switch OFF.

Judgment value of timer after engine starting
t = 455 - 27 x Ti
Ti is the lowest coolant temperature after starting the engine.
Time Needed for Diagnosis: To be determined. (It is varied by the Min. engine coolant temperature and engine conditions such as vehicle speed and engine coolant temperature.)
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
