Started the car noticed a rattling noise near the belt area, seemed to be something hitting the timing belt cover. Was trying to get the work so. . . hope and pray? Any way not far from home something sounded like it “unwound”. Stopped in a parking lot with engine running, alternator A/C and power steering pump belt still okay. Started driving home. Close to home the car started bucking and CEL flashed, pushed in the clutch and it smoothed out. Had to do that a couple times. Got it in the garage. The car starts and idles (after sitting long enough to have cold coolant I opened the radiator), no coolant in the oil, no coolant leak, no pistons hitting the valves. Got the scanner from AZone and the codes are P0336 crank position sensor, Honda Enhanced code is CPK Sensor Range, and P0300-P0304 all cylinders misfired and random misfire. I changed the timing belt, water pump, and tensioner earlier in the summer, not Honda OE parts (Eric is going to say that was the failure but go ahead and say it anyway). I haven’t actually pulled anything apart yet, but the unwinding sounded like something with a bad bearing spinning up and then seizing. Tensioner? WP? or the sensor rubbing against the belt?
As far as the sensor I can’t remember if what it reads from is removable from the crank or even what it is called. Since I’m going to have to likely re-change the timing belt. . . anything else recommended at that level of disassembly? Other problem we’re about to get some really unfriendly weather here just north of STL.
Also I got the appropriate Vmanual for the timing belt, that may make things easier. Valve cover gasket leaks some oil. Maybe because it’s not flat?

I don’t know these answers: Does the Honda Control Module or computer allow the engine to idle without crank/cam pos sensor? Are those sensors just for controlling spark/injector for engine speeds higher than idle?
I’m just trying to figure out what I may find/need before I tear into it, nice weather next weekend (who believes a weatherman?). I rarely have time to diagnose/get parts/fix in the time I have available. Wait who does?
Funny. Just last week I ran into this.
The issue was that the previous timing belt was not installed correctly. They had damaged the tensioner and caused the belt to fail. Considering you were in there recently, perhaps it’s time to go back in and have a look.

Good luck and keep us posted.
Wow. . that belt is for a skinny Honda.
Yeah I remember instructions for the spring on the tensioner saying to make sure the hook was in a certain direction. . . the hard way to hook it. It looks like Honda belt and tensioner this time around. I don’t think the replacement had the stop on it.
Bought an inspection camera the other day and took a peak, there is residue from the belt. The width and “teeth” of the belt look okay, I think that the tensioner did lock and caused it to slip.
Get to go to the almost farthest away dealer in the STL area tomorrow to get a belt and tensioner.
Eric, any other tips on the tensioner itself? Got to watch the vid a few more times.
BTW the tensioner is called an eccentric with the bolt hole not on the center with the rotating axis. I like to take out the air filter box, makes getting the valve cover off and especially on easier. Also, its a nice place to store some of the nuts/bolts from the top of the engine that can’t be “left in the part” while it’s uninstalled.
The spring lodged on the crank sensor. . . melted it. Lower belt cover was rubbing against the crank damper causing the rattle. Used a torque wrench this time on the tensioner. I think I over tightened it last time. . . Maybe I got lucky. No I didn’t the car I borrowed to go to work last week got backed into and needs a new driver’s side rear door. Did I mention it’s an Oldsmobile Aurora? Some one at work sent a nasty e-mail to the office and some how I’m catching the fallout.
