General
- Firing Order: Engine Firing order, used for misfire
detection
TPS Sensor
- P0121 Max MAP: The VCM will calculate an expected TPS
position in two MAP ranges. If the MAP is less than MinMAP then it
will use one table to calculated expected TPS, if MAP is greater
than MaxMAP it will use a different TPS calculation table. To
disable this test set MaxMAP to 100.
- P0121 Min MAP: The VCM will calculate an expected TPS
position in two MAP ranges. If the MAP is less than MinMAP then it
will use one table to calculated expected TPS, if MAP is greater
than MaxMAP it will use a different TPS calculation table. To
disable this test set MinMAP to 0.
- Calculated Airflow vs. TPS% vs. RPM - P1514/P0068 Error:
The VCM uses this table to determine the maximum airflow/cylair the
Electronic Throttle should be passing at a certain TPS position and
RPM. If the measured cylair/airflow exceeds this value then
P1514/P0068 is set.
Diagnostic Tests
- P0101, P0106, P0121 Min ECT: ECT must be above this for
the tests to run.
- P0101, P0106, P0121 Max ECT: ECT must be below this for
the tests to run.
- P0068 Enable RPM: RPM must be above this for the tests
to run.
