How to resolve fault code 01314?
2 Answers
Because some components share a common positive power supply or common ground that has malfunctioned. After reviewing the relevant circuit diagrams, it was found that the components with the fault code do not share a common positive power supply or common ground. Check the computer or wiring harness for related issues, as the wiring harness is most prone to problems. To troubleshoot, replace the wiring harness connected to the small plug of the engine control unit.
Sigh, I've encountered the trouble code 01314 several times during my long drives. This code usually indicates a circuit issue with the engine control module, such as a relay or power line failure, which might prevent the car from starting or cause erratic shaking. My first suggestion is to use an OBD-II scanner to read the specific cause—you can rent an affordable one at supermarkets or online. Sometimes the problem is simple: a blown fuse or a loose connector, so check and tighten them. If that doesn't work, try clearing the code; if it reappears after restarting, deeper investigation is needed. Once, I replaced a relay and the issue was resolved immediately, but the relay was in a hidden spot—the manual or video tutorials were a big help. Don't delay, as this fault can cause unstable driving, especially on highways, posing serious risks. It's best to perform regular maintenance and check the circuits to prevent issues in older cars. If you can't fix it yourself, head straight to a repair shop—professional technicians can handle it accurately and safely.
