SSM72178

"ISSUE: THE MIL IS ILLUMINATED AND P2183-00 IS STORED IN THE PCM, BUT WITH NO DRIVEABILITY CONCERNS RAISED BY THE CUSTOMER. CAUSE: THE P2183-00 CODE IS SET WHEN THE PCM DETECTS A PROBLEM WITH THE TEMPERATURE READING FROM THE 'ENGINE COOLANT TEMPERATURE SENSOR 2 CIRCUIT'. IF THE LONG TERM AVERAGE VALUE IS STUCK (MOVEMENT OF SENSOR VALUE IS NOT AS EXPECTED DURING A MONITORED DRIVE CYCLE), THE CODE WILL SET."
