Car model and year: 2005 Nissan Pathfinder 2.5 T-Spec
I’ve always had one kicking about to do the EML engine dash light to find basic errors. But was asked to help clear a DPF flashing light on a family members Mazda5…..
Took it up the road, ragged in 3rd gear 4000rpm at 60mph for 5 miles so well warm and ready to go, plugged in the scanner and went through the options to force a DPF clean.. and get this all the time.
When your Nissan check engine light stays on, it means the onboard diagnostic system of your vehicle has detected a malfunction with the way the engine is running, a problem with the emission system and in some cases, it can indicate a transmission problem. To find out the fault code a short description of the problem you can read the codes using an Nissan OBD2 code scanner.
Tools to use and reviews:
1.I use a Foxwell NT301. Thought I’d only use it once or twice, but I was wrong. Having your own scanner is so convenient.
2.I use an Autel MX808 MaxiCheck which I picked up under $500 about 15 months ago. It works with any passenger car or truck with an OBD II port, but for another $99, you can get the OBD I kit which has the connectors for a number of manufacturers OBD I diagnostic ports. MK808 is the scan tool with the OBD I kit. It’s pretty nice! It’s a lot quicker than my former boss’s X431 Launch diagnostic tool and his older OTC Genesys tool. It does an all system code scan, can monitor/graph/read live datastream info, read freeze frame data, can be used to relearn throttle bodies and register TPMS sensor, relearn idle air volume, relearn steering position and a bunch of other stuff. It can update wirelessly and the updates after the first years are reasonably priced. Autel has a number of tools, both less and more expensive. This one was perfect for me and for what I do at home.
3.I used a Nissan Consult III scan tool to read and clear the engine system codes.
1). Locate the diagnostic port under the dashboard and plug in your Nissan Consult III.
2). Turn on ignition but do not start the engine.
3) Allow your Consult III scanner to turn on. Press Enter to read codes.
