I just received a failed emissions test due to a fail in the on board computer. Below are details on the report.

Under the on board diagnostics readiness monitors, I get a NOT READY under the "Evaporate" section.

As for the actual codes that come up: P07170, P0173- Fuel trim bank 1, 2. P0700 Transmission Control Syatem (MIL Request). P0711- Transmission fluid temp Sensor A circuit range/rerformance

Have the transmission codes checked first. It could be a loose or contaminated connector at the transmission. The connector leads to the valve bosy and temperature sensore. Unplug it and check for contaminations.

As to fuel trim, check for vacuum leakages, spark plugs etc.
