2003 Honda Pilot VTM-4 issues


Topic starter

Got a 2003 Honda Pilot with 200,300 miles on er. Regular maintenance, engine purrs and trans “shifts like a dream”; success story of how regular maintenance will carry a good vehicle a long time.

VTM-4 light pops on the dashboard after driving for 30 seconds or so/ going 20-25 ish miles per hour.

However, going at lower speeds (below the aforementioned speed) I can still activate VTM-4.

This has been happening for a few months, so I did a drain and refill of the rear diff with Honda genuine VTM-4 fluid, as well as changed out the VTM-4 sensor (aka oil temperature sensor), with a Honda genuine oil temperature sensor.

No joy... VTM-4 light still pops on.

I haven’t actually put it up on jack stands to see if all 4 wheels are engaging.

Any advice?

ps-this is one of the greatest informational hubs on the internet

I should also add, I did a scan using the OBDII scanner Scotty recommended in his “this scan tool changes everything” video.

No codes popped up.

Well those systems are very touchy as they age first jacket up and see if the things actually working if it is I would ignore it if not you really going to have to find somebody like me with a dealer level scan tool to do bi-directional testing to see if perhaps a solenoid is wrong

Yea I’ll definitely do that.

I drove it around on some wet grass and the 4wd seemed to be working, but again, right when I start approaching 25 mph, VTM-4 light goes on.

Checked all the wiring going to the rear diff, no fraying and everything seems to be plugged in.

This car is a great vehicle . I hope to restore it to its former glory.

Also, Scotty, I appreciate the response!
