OK so I have AD17A1 head and it has AD17A2 block. Can get running but crankshaft center code. Keeps coming back brand new sensor everything time and is dead set. But the crank shaft that is in it is from the D17A1 block. Since the D17A2 block spun a bearing I used the good crank but is this the reason that it keeps throwing that code and putin my ecu in to limp mode? Please I'm trying to figure this out. Before having to buy a whole new block.

what actual code are you getting, P0335? The crankshaft itself is interchangeable between D17A1 and D17A2, so there's no issue there.

If you're using non-OEM sensors (i.e. not purchased from Honda or otherwise non-Denso branded for most, if not all of the sensors), ECU prolly won't play nice with them. Furthermore, if it's the crankshaft position sensor, that thing is pretty damn finicky. If you drop it, from any height, torque it down too hard, jostle it, call it funny names and hurt its feelings, then it'll malfunction on you and the only real fix is to replace the sensor.

Case in point, I accidentally dropped my CKP sensor 6 inches onto a folded microfiber towel and that was enough to make it not play. Another time later down the road, I torqued it down a bit too much (admittedly, felt like something clicked when I tightened it down), and that one didn't want to play. When I replaced with new Honda OEM ones and handled them like a Faberge egg and used an in-lb torque wrench to install, all issues were alleviated.

It's given me a p0339 code Crank shaft position sensor a circuit intermittent... is the code and no its brand new out he box never dropped and it's a 70 dollar one from the part store but now the crankshaft Isn't the original one that came in that block? The crank shaft is a d seventeen a one but the block is a d seventeen a twoIsn't the original one that came in that block? The crank shaft is AD17A1 but the block is AD17A2.

Everything below the head is the same on the two engines. Return the parts store sensor and get and oe one

only exception are the pistons in the -A1 vs -A2. -A2 has pistons that give it a higher compression ratio. That won't cause any issues though.

Is the sensor you got from the parts store a Denso branded sensor, or is it a parts store house brand (like AutoZone's Duralast)?

It's a Dorman and has a lifetime warranty so just in case low an the pistons are the same everything is the same other then the crankshaft... only reason Is because the block spun a bearing and crank was a little Scared so I used my old one out of the d17a1 cuz my timing belt tensioner hole got passed around way To many times if u get me...

hondas no like aftermarket sensors. Denso or NTK only
