# Service bulletin 18\-016\-13

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10188643
- Published by NHTSA: 2021\-03\-15
- Manufacturer's number: 18\-016\-13
- Manufacturer's date: 2013\-04\-04
- NHTSA component: ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\)

## NHTSA's summary

This bulletin involves reprogramming the Powertrain Control Module with new software. The Technician may discover that P0128 \- Thermostat Rationality DTC is present. This DTC is a two trip code and is matured if a significant difference exists between the PCM predicted and actual engine coolant temperature during engine warm\-ups. The PCM calibration may improperly mature a P0128 DTC because the airflow across the coolant temperature sensor during colder ambient temperatures, 50° F \(10° C\) or below, causes the predicted coolant temperature to deviate from the actual coolant temperature.
