October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Set Condition

After a calibrated amount of cool down time, the Powertrain Control Module (PCM) compares the AAT, ECT and IAT Sensor values. If the general temperature rationality passes, the PCM compares the Oil Temperature Sensor value to a threshold based on the other temp sensor values. If the difference is greater than 15°C (27°F) the diagnostic fails.
