I'm getting a P0107 code and it's pointing to my map sensor. Dealership gave me part # 89421-47010, but I pull out what I think is the map sensor and I have part # 89421-52010 which is also a MAP sensor part. I tried cleaning it, but it is still throwing a fault code. I'm going to order the new part, but I'm unsure if there's a difference between the part # the dealer gave me and the part # I found on my vehicle.

If I didn't find the correct map sensor, could you please point me in the right direction? See pics attached.

Map sensor?

Dealership gave me 89421-47010. This one is 89421-52010

You might want to check resistance on the original's terminals. I attached FSM info. It could also be wiring or ECM.

Looking at that PN... it appears that MAP sensor is used in a lot of vehicles.

Those part numbers seem to vary based on the chassis code for the GX.

GKTGKA - 47010
GKTZKA - 52010

I still don't know exactly what the difference is between the Z and the G, and both point to the 4.6L V8 in the US models, so as it relates to that sensor I'd be 99.9% sure there's no difference. I suppose you could play it super safe and replace it with the part number you already have - your call.

I ordered a new part (the existing one) and still have a fault P0107. Beginning to think it's in the harness.

Actually, I’m getting 4.9 V from PIM. Maybe it’s not the harness after all.

I was just poking around under the dash/steering wheel. I spotted a small square ish sensor appropriately 1/2”x1” and it’s marked MAP. Could that be what you’re looking for?

^Ha! It’s fairly obvious when you look under the dash plus it’s already past my bedtime. Lol
Will try tomorrow if the OP is interested.

I didn’t get any voltage across the VC and E2 when MAP is disconnected. When I connected mAP and measured voltage across (two paper clips), I got a solid 5V. I thought it was supposed to be variable voltage based on the change in pressure, but it’s consistent. I got a “New” map sensor and it’s still throwing P0107 code.
