A: No. The code specifically targets the bypass valve, not the main thermostat. However, replacing both components together is often good preventative maintenance.
: Energy Management Control / Electrical Energy Management System. General Behavior
If you own a modern Nissan vehicle—especially models like the Rogue, Altima, Sentra, or Pathfinder—and your check engine light has just illuminated, you might be staring at a code that reads after a scan. Unlike common oxygen sensor or misfire codes, this one often leaves drivers and even some novice mechanics scratching their heads.
Use a multimeter to check the resistance between the two heater wires (usually the same color, like two white or two black wires). A healthy Nissan sensor typically reads between 2 and 10 ohms Check Fuses:
Key Features
After repairs, the code often requires a "Hard Reset" using a professional-grade diagnostic scanner to clear the "SCR System Fault" and end any limp-mode conditions.
Assuming you mean a feature description/spec sheet for the Nissan P155B-00 (engine control module / part), here’s a concise feature spec. I’ll assume OEM replacement module functionality for a modern Nissan vehicle — tell me if you want it targeted to a specific model/year.
: Open or shorted circuits in the wiring harness connecting the Engine Control Module (ECM) to the battery heater relay. Blown Fuse
