Answer 1

HI there,

This can indicate issues with the wiring harness or the fuses for the sensors, and also an issue with the PCM. Sometimes a bad ground can cause this issue as well. Check and make sure all the grounds from the engine to the body are in good condition. Some known causes of this type of issue are broken grounds from the engine to the firewall.
