After diagnosing a faulty crank angle sensor on my AP1 I set forth to replace it.

Its not the easiest to get to & so far i have removed water pump pulley, belt pre tensioner & alternator. This has given me enough room to get the sensor out but the plug & wiring to the sensor goes behind a water pipe & there is not enough clearance to pull the plug through (even though I unbolted the pipe where its bolted to the block).

It looks like i have to drain the coolant & remove at least one end of the pipe to allow the plug to pass through. I ran out of time to do this on the weekend so i will tackle this next weekend. But I'm curious if anyone has found an easier way to remove the sensor as i find it hard to believe Honda made it so ridiculously hard to replace.

Any ideas?

Be 100% sure that is your problem, as I have never seen a single bad one to date.

If you depin the connector there should be enough clearance to remove it without messing with the water pipes.
Billman has a good point though.

Thank you both for your advice. I'm confident with my diagnosis at the error was straight from my scanner. Checked the resistance between pins 1 & 2 had open circuit.

I've been chasing this fault for a while. Intermittently the engine would idle ok but anything over 1000 rpm & it would break up & go into limp mode. Turn it off for a while & it would usually be ok. It would always log the same error, but the sensor checkout ok every time i tested it . But this time it was open circuit.

I'll try to depin but i think you need a tool for the DT connector

A very fine 1-2mm flat head screwdriver is usually enough for de-pinning.
Can't remember the connector style but I got a spare sensor laying in my garage so will check later today.

Just did a check and it's really easy to de-pin, first you pull the white plastic thing straight out.
Then you got this view bellow, carefully push the metal pin up and at the same time pull on the cable, it should come out pretty easy.
Just for reference my sensor measured 2100ohm between 1 and 2.

Not wanting to bring back from the dead but I have the same problem. What was the fix?

Is it possible for a bad OE TCT to disturb the timing chain just enough that it triggers a crank position fault?

Billman250

No sir. That would be off-sync, not a sensor hard fault.

Can this sensor prevent the car from starting. I think that's my issue.
