ok i just got done doing my obd1 conversion and its throwing some codes its throwing a 4 and 41 the 41 is due to the o2 sensor i think. the 4 is the crank angle postion sensor. nowmy question is before i did the conversion it never had any codes never had the crank angle problem at all i am also running a p06 that will be converted to a p28 i just used the p06 to start it to make sure that everythign is done right. what would cause it to throw the code 4 any help would be appreciated

 

oh yeah also the motor is a obd2 hx d16y5 and its a hx obd2 distributor the motor and dizzy is from a 98 i dont know if the crank angle sensor is somewhere else on the motor? also when i get it tuned will the tuner be able to disable that code with no issues and it still run right?

 

Sounds like a bad wire in the conversion hanress. Leave the harness connected and run a continuity test from the ecu conversion harness to the crank angle sensor wires on the distributor plug. There are two wires related to the crank angle sensor. If you don't have continuity with the harness attached try it without and use the obd2 pinouts. Sounds like a wire has a break or is crossed.

Tuner won't be able to do much if your car has a code 4. Don't worry about the 41.

 

ok well can the crank angle sensor be on the crank? i found a plug by the crank that has 3 wires. i am going to try to run some wires to see if thats where it is at.

 

That is the crank fluctuation sensor. It is used to detect missfires and is not a true crank angle sensor. That is an obd2 only sensor and the obd1 ecu will not throw a code if that sensor is broken or unplugged. Your problem is elsewhere.
