2022年9月15日 · The P0315 code stands for “Crankshaft Position System Variation Not Learned”. It’s usually related to an electrical or computer fault. Some of the problems that could trigger the code are an improperly performed crankshaft position relearn procedure, a faulty crankshaft position sensor, and PCM problems.

2022年6月13日 · Repair Information for P0315 Chevrolet code. Learn what Crankshaft Position System Variation Not Learned means, location and how to repair?

Locate the Crankshaft Position Sensor on your particular vehicle. Once located, visually inspect the connectors and wiring. Look for chafing, rubbing, bare wires, burn spots or melted plastic. Pull the connectors apart and carefully inspect the terminals (the metal parts) inside the connectors.

2022年6月13日 · What causes the OBDII code P0315 in a Chevrolet to be triggered? - The code is usually triggered when the engine control module (ECM) detects that the crankshaft position variation has not been learned.

2023年8月19日 · P0315 relearn procedure is a function you must perform after replacing/repairing a crankshaft position (CKP) sensor. P0315 DTC shows up when there is data collected by CKP that is not present in the memory of the powertrain control module PCM. So P0315 relearn refers to the CKP sensors’ relearn process.

Code P0315 indicates that the engine control module (ECM) has not completed the crankshaft position system variation learning procedure, which is essential for accurate timing and engine performance. This often occurs after battery disconnection, ECM replacement, or major engine repairs and requires recalibration using a diagnostic tool.

The P0315 diagnostic trouble code (DTC) indicates that the crankshaft position system variation is not learned by the vehicle's engine control module (ECM). This means that the ECM has not been able to determine the correct position of the crankshaft in relation to the engine's timing.

OBD-II Code P0315 is defined as a Crankshaft Position System Variation not Learned. The Crankshaft Position Sensor measures the exact rotational speed and position of the crankshaft. This provides a critical data signal used by the engine control module (PCM) to control Ignition Spark Timing and Fuel Delivery.

2018年7月30日 · OBD II fault code P0315 is a generic code that is defined as “Crankshaft position system – variation not learned”, and is set when the PCM (Powertrain Control Module) detects a variation between the actual and stored crankshaft position reference points that exceeds either a specified limit, or when the manufacturers’ prescribed ...

What Is the P0315 Code? Can I Still Drive? The P0315 code indicates that the crankshaft position sensor (CKP sensor) has gathered certain information about your crankshaft position that wasn’t...
