DTC Troubleshooting: P00B6(3.0L Engine): Notes
DTC P00B6 : Engine Coolant Temperature (ECT) Sensor 2 Incorrect Correlation
NOTICE:
Before you troubleshoot, review the How to Troubleshoot - Refer to: How to Troubleshoot the Fuel and Emissions Systems(2.0L Engine) or How to Troubleshoot the Fuel and Emissions Systems(3.0L Engine) .
- Do not use an engine block heater because the engine coolant temperature will not stay equal during engine stop.
- When an ambient temperature extremely changes, malfunction judgment may not execute. Avoid extreme temperature changing condition after or before engine start. (When the vehicle is parked in the garage, open the garage door to introduce outside air; then start the engine.)
