The issue I have come across on my brothers 03 mdx is that I have swapped out the sensor and did a fluid service. The light turned off temporarily but switched back on within an hour of driving (30 miles around town intermittently). When I put the screws back on nothing leaked and I secured the sensor plug without breaking the fastener so it shouldn’t be the plug itself. I used Honda genuine fluid and the Oem sensor. Should I check fuses or follow the wiring harness? Also, could another part aside from the sensor cause the light? It’s got just over 100k miles and the fluid looked to be recently serviced before he bought it, as a small amount of metal shavings were in the fluid. Could the differential possibly be worn out? I never pulled the differential cover to see it internally. Thanks in advance.
