DPF Warning Light on a Toyota Land Cruiser Prado
Investigate soon. Driving short distances is generally okay, but book a diagnostic check.
What the DPF Warning Light Means on a Toyota Land Cruiser Prado
The DPF light on a diesel Toyota Land Cruiser Prado means the diesel particulate filter is clogging with soot and needs to regenerate (burn it off). Catch it early with a steady motorway drive and you avoid an expensive forced regeneration or filter replacement.
How Urgent Is the DPF Warning Light?
How worried should you be? For the DPF Warning Light on a Toyota Land Cruiser Prado, the urgency is moderate. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Toyota Land Cruiser Prado still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Alongside the DPF Warning Light, Toyota Land Cruiser Prado owners commonly report a handful of related signs. Some are obvious, others easy to miss until you pay attention.

How to Fix the DPF Warning Light on a Toyota Land Cruiser Prado
To resolve the DPF Warning Light on your Toyota Land Cruiser Prado, resist the urge to simply disconnect the battery and hope it stays off.

|---|---|
P2002 |
Diesel Particulate Filter Efficiency Below Threshold (Bank 1) The DPF is not trapping soot effectively or a differential pressure sensor is misreading. |

Will the DPF Warning Light reset itself on a Toyota Land Cruiser Prado?
