Generic OBDII Parameter Identification Values

FOOTNOTES

The footnotes are referenced throughout the Diagnostic Reference Value Charts. A letter appears in parentheses next to a value indicating supplemental information is applicable.

Reference values may vary +/- 20% depending on operating conditions and other factors. RPM values are axle and tire dependent.

Downstream O2S(12, 22) will only switch lean to rich when catalyst monitor is active.

Refer to Parameter Identification Access, for PID descriptions.


A A/C On.

B Cooling fan On (single, low or high speed).

C O2S(s) should switch from rich to lean at least once every 3 seconds. O2S voltage should toggle above and below 0.450 DCV and never be a negative value. Valid O2S switching only occurs during closed loop fuel control.

D Downstream O2S(s) will stay at a constant voltage when the catalyst monitor is Off (positive value only). When the catalyst monitor is On, O2S will switch rich to lean above and below 0.450 DCV and never be a negative value.

E Brake pedal depressed.

F Catalyst Monitor Off.

G With Transmission Control Switch (TCS) On, overdrive enabled.

H Values shown are commanded by the PCM and may not be actual.

I Steering wheel turned.

J Clutch pedal depressed.
