What does Land Rover P1315 code mean?
The misfire monitor operates continuously and is designed to detect misfire levels that could cause thermal damage to the catalyst or excessive exhaust emissions. Misfire determination is done by analyzing crankshaft speed changes, since a misfire will cause a speed drop. Essentially, the monitor determines the time required for the crankshaft to travel 180 degrees (4 cylinders only) for the current firing event and compares it to the time required for the previous firing event. If the time required for the “current” firing is longer than the previous firing, then a misfire is considered to have occurred.
