So I have the Crankshaft Sensor Code, I removed all 3 belts and the crank pulley, and replaced with a brand new sensor, the code was still showing up, so I noticed that the wire coming from the harness was damaged from rubbing on the alternator belt, I have since rewired it soldered a new wire to the sensor, but I am still getting the p1336 code, I have also tried pulling the radio fuse for about 2 minutes then starting the car, the engine light comes back after about 3 seconds, the car is drivable in this state, but it is running very rich and will never pass emissions, I do have some time (2 months) before emissions testing, but I would like to take care of this issue asap. I have tested all the interior fuses and they are good, working on testing all of the fuses under the hood, but I have to pull them individually since my fuse tester won't fit in there. Any advice would be appreciated, I am a student so I really can't afford to pay a shop here, I would say my mechanical skill level is moderate to advanced.

 

Quick update, I have tested all the fuses under the hood and they are all good. Not a single bad fuse in the vehicle, it is also worth mentioning the previous owner had an aftermarket stereo, and they had removed the subwoofer and amplifier before selling the vehicle, so I went ahead and removed all the extra stereo wiring, but still getting the code. Is the radio wiring and crankshaft sensor wiring closely related? Also is there anyone with a wiring diagram?

I have discovered the problem wire, it is a blue wire with a pink stripe, except the wire going to my sensor is a thicker gauge brown wire, there is also the same wire at the ECU, blue with pink stripe, but this brown wire has been spliced in somewhere, I have started tearing apart the harness, to see at which point the wire is spliced. it might be easier to just bypass the entire harness and run a brand new wire from the ECU to the sensor, but I need to make sure with a wiring diagram that this is in fact the correct wire, can anyone confirm this? or have any sources.

 

OK I have found this wiring diagram for the ECU. it appears the wire I am looking at is the correct wire, which would be number 22 on connector C. it is a Blue Wire With Red Stripe.
I am going to try and run a whole new wire from the ECU to the sensor, and see if this resolves the problem.

 

OK, I have replaced the CKF sensor, rewired it to the ECU with brand new wires, I have also replaced the distributor, still no luck, I was able to drive around for about 50 miles and the engine light came right back, the car engine idles very rough, and its running an excessively rich mixture, I am pretty sure the Cats are done at this point. not really sure what to do, I am using a duralast CKF sensor from autozone, its brand new sensor, I can try going to the honda dealer and get an OEM sensor, but I have a feeling this is some sort of computer issue, I have tried the CKF wiring bypass trick as well, same thing, engine light went away, but the motor is still idling very rough and running rich, then the light came back shortly after.

 

This is probably your main problem.

Also did you run the CKF wires in a shield? That segment of harness is shielded to protect it from noise. It is a very electrically sensitive circuit.

 

I already removed that wiring, and did the bypass trick explained here https://technet.ff-squad.com/ckftrick.htm
currently the sensor is not plugged in, the ECU is piggy backing the sensor in the distributor. the problem is still occuring. distributor is also brand new.

 

I have been trying to tackle this wiring issue for weeks, re wired it, that didn't work, so I did the bypass trick, still didn't work, there doesn't seem to be anything wrong with the sensor either, I measured the sensor from PIN 1 and PIN 3, got 2.5 ohms on the reading so the sensors is testing good.
Upon further inspection I have discovered the alternator bearings are worn, this is causing the alternator to rattle/click when cold starting, I am thinking perhaps there is not sufficient voltage being supplied by the system, or maybe even excessive electrical noise in the system due to the bad alternator. I am hoping this is the solution, I will try changing out the alternator, and report back with my findings.

 

What was your follow up findings?

 

Im needing help please. This is my daughter's vehicle that just graduated highschool and in college. We thought she had gotten bad gas. Pumped it out, replaced the fuel pump and filter. It coded for crank sensor, I've replaced it and now the vehicle will not do anything. I was only getting 1.9v to the crank sensor so I installed a referb ecm and now I can't get any power off the ecm pin. I have a feeling this is something simple but I need help please! I just had a newborn baby so my time is limited and financially we are strapped. Daughter works and college so she's currently got our vehicle. Please help me.
