Question for the pros...I bought a 1995 Accord LX 2.2L for my son (first car). I figured working on it would be a good way to spend some quality father son time...The engine had a broken camshaft. So I opted for an engine swap. I located the lowest mileage one and we matched every number that was possible. After 1 week of work, we managed to get new motor mounts, radiator and new engine back in place. To my surprise, this engine has what looks to be a Crankshaft position sensor plug...The original one didn't! Obviously, I can't get it to start - otherwise i wouldn't ask for your help! What can I do to modify? Distributor? Wiring? Any help would be greatly appreciated!!

 

If the replacement engine is from a 96/97 then it is slightly different. But will run by copying what was on the 95

 

Difference is that the 94-95 F22B1/2 engines were OBD1 and the 96-97 F22B1/2 engines were OBD2a

IIRC you can use the distributor from your original engine. The TDC and CYP sensors are located in the distributor for the 94-95 model. Where as they are wired and mounted to the oil pump housing behind the crank pulley on the 96-97 model.

 

So it is as simple as removing the old distributor and replacing it with the one from the old engine?

 

the sensor at the crank is a crank variation sensor, if you have everything right and the motor is good it should crank regardless of that sensor.the cam sensor reads twice engine speed so no need for a crank sensor.everything you need for spark timing is in the distributor

 

Yes one of the sensors is used as a crank speed variation sensor. However it is not known as a crank variation sensor, it is the TDC sensor.

• TDC sensor determines ignition timing at start up (cranking) also detects when crank angle is abnormal during operation.

• CKP sensor determines timing for fuel and ignition of each cylinder and also detects engine speed.

The only sensor found in the OBD2 distributor is the CYP sensor. It detects the position of cylinder No.1 for sequential fuel injection to each cylinder. Without the TDC or CKP it's useless......

 

Thank you - I will remove the old distributor out of the bad engine and swap them.

 

i have a 95 accord with a swapped motor from a 97 im in limp mode like i lose power on top end its non vtec. i have a obd1 car with a obd2 motor auto ecu obd1 and a auto harness obd1 so i gotta swap the ecu and harness but swapping motor what motor? h22? f22? and yea everything is in the distributor its easier

 

Quick Update: I unscrewed the distributor to remove and I discovered that my son left one of the wires under the distributor unplugged! I plugged it in and the car started. Now comes the strange part...The car didn't start at first key, it would turn and turn and then when I released the key it would catch and start. It did run, but I had no Tachometer. I checked the forums and noticed that it may be a common problem associated with the ignition coil. I replaced the coil. Now i can't get it to start again. I swapped coils back and still no start. There is fuel, I can smell it. Plugs look good. I tried to pull the codes using the "bridging' method - however the CEL light blinks continously and I am unable to deduce an actual code. It just blinks in a slow and continuous sequence! Any input?

 

Which dist is in it, I hope the one from the 95.

Also double check the main ground on the drivers end of the TB, be sure it is clean and tight.
