[quote=”jedwa1216″ post=197631]”I’d try doing the crankshaft position sensor relearn procedure”
I thought that for a few months as well and did try it a few times but what I have learned is that the relearn procedure is for optimization. It will not fix a problem nor will it cause a problem that is bad enough to throw the code. There are several videos and forums online from Honda and Acura techs where they quote that they have changed hundreds of timing belts and have never performed the relearn procedure with no problems at all.[/quote]
Glad the issue is fixed.
I just finished doing some repairs and maintenance on my 07 Odyssey. One of the things I did was this TSB (08-0145), which says:
21. Do the CKP pattern clear/CKP pattern learn
procedure. Go to the appropriate procedure below.
NOTE: If you don’t do the CKP pattern clear/learn
procedure, the ECM/PCM may detect misfire when
there is none, and possibly set DTC(s) P0300
through P0306.http://www.urvi.net/forumfiles/SB/A08-045.PDF
It’s not clear if they mean it should be done even if the CKP sensor or drive pulley was not removed.

Interesting, I didn’t know that it wouldn’t cause a code if not done.
I agree it only needs to be done if removing/replacing a crank sensor, not just a timing belt.
Bleeding the PS fluid might help–removing air + new fluid.
The Odyssey has similar issues, and one fix for it is a new PS reservoir which is about $15.
I used to have a 92 Accord, and the distributor/ignition module was a common problem, as was the oil leak. Just a guess, but I think it could trigger all of those codes.
Unless it has been done recently, I’d want to clean the injectors anyway just based on age and mileage. I don’t know of a way to test the fuel cap. The gasket could look fine and hiss, yet still not hold sufficient pressure. Make sure you’re tightening it until it clicks a few times.
Maybe clean MAF if present? (And check for leaks in the air intake after it.)
I think a 43 could indicate an O2 sensor wiring issue also–might want to check the wires and connections.
I think it could also be an exhaust or converter leak/obstruction giving your O2 sensor wacky data.
If there’s a noticeable rough idle which improves with increased rpm, that seems to point a bit more to a vac or air leak.
Check the timing until you are 100% confident in it. 🙂 Actually, turn the engine only by hand from the crankshaft pulley bolt with the spark plugs removed until you are 100% confident. Stop if there’s any resistance.
If timing is good, do a compression test.
In this order, I’d try:
fuel cap replacement
vacuum leaks/disconnected hoses
injector cleaning
fuel pressure
injector function
