What does the code P1492 mean?
What does the code P1492 mean?
P1492 Ambient / Battery Temp Sensor Too High.
What is a battery temperature sensor?
The battery temperature sensor allows the charge controller to adjust the charge voltage based on the actual battery temperature continuously. Temperature compensation of charge voltage assures that the battery receives the proper charge voltage as battery temperature changes during normal operation.
How do I know if my battery temperature sensor is bad?
Symptoms of a Bad or Failing Battery Temperature Sensor
- Engine surging. One of the most common symptoms of a failing battery temperature sensor is an engine that surges during operation.
- Low battery voltage. A low battery voltage can be another symptom of a failing battery temperature sensor.
- Warning light.
How do I know if my battery sensor is bad?
When the battery current sensor fails, the vehicle will not charge correctly, leading to a DTC or a dead battery….Common signs of failure include:
- Irregular charging rates.
- Low battery voltage.
- Corrosion on the battery or sensor connection.
- Broken or bare sensor cabling.
How do you fix P0138?
What repairs can fix the P0138 code?
- Replacing the O2 sensor for bank 1 sensor 2.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
- Replacing the catalyst in front of the sensor.
- Repairing a leaking injector.
What happens when a battery temperature sensor goes bad?
If the computer is receiving an incorrect signal from the battery temperature sensor, it can stop a proper charging and cause low voltage. The vehicle with a low voltage is hard to start, and may also cause other problems for the vehicle’s electrical system.
Can you drive with a bad battery sensor?
Having a damaged battery temperature sensor can prove to be very problematic for your charging system. Driving your car with a damaged sensor may lead to problems cranking the vehicle when needed.
