Normal Scan Data Values

CONSULT Reference Value in Data Monitor Mode











Remarks:
- Specification data are reference values.
- Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.

(i.e., Adjust ignition timing with a timing light before monitoring IGN TIMING. Specification data might be displayed even when ignition timing is not adjusted to specification. This IGN TIMING monitors the data calculated by the ECM according to the input signals from the camshaft position sensor and other ignition timing related sensors.)
- If the real-time diagnosis results are NG, and the on board diagnostic system results are OK, when diagnosing the mass air flow sensor, first check to see if the fuel pump control circuit is normal.

The following are the major sensor reference graphs in "DATA MONITOR" mode. (Select "HI SPEED" in "DATA MONITOR" with CONSULT)




THRTL POS SEN, ABSOL TH.P/S, CLSD THL POS
In the image(s) is the data for "THRTL POS SEN", "ABSOL TH.P/S" and "CLSD THL POS" when depressing the accelerator pedal with the ignition switch "ON".

The signal of "THRTL POS SEN" and "ABSOL TH.P/S" should rise gradually without any intermittent drop or rise after "CLSD THL POS" is changed from "ON" to "OFF".







CMPS-RPM (REF), MAS AIR/FL SE, THRTL POS SEN, RR O2 SEN, FR O2 SEN, INJ PULSE
In the image(s) is the data for "CMPS-RPM (REF)", "MAS AIR/FL SE", "THRTL POS SEN", "RR O2 SEN" "FR O2 SEN" and "INJ PULSE" when rewing engine quickly up to 4,800 rpm under no load after warming up engine to normal operating temperature.

Each value is for reference; the exact value may vary.
