I'm on the tail end of completing my TBI to TPI swap. I'm currently getting SES Code 43 (knock sensor).

I ended up using the original TBI knock sensor since I had looked up if the sensors were different and the info I found at the time had said that they were not. Now that I'm getting an SES code I looked it up again and the part numbers are different for a 305 TBI sensor and a 305 TPI sensor (which is what I should have done to begin with!).

Does anyone know if these knock sensors are interchange able between the TBI and TPI? I'd rather know that it is, in fact, different before I pull the knock sensor out and flood my nicely redone engine bay with coolant.

Thanks in advance for the info!

 

One thread asking this question is more than enough !

 

nothing is never enough when you're hot pressed to finish a project

 

No
And you also realize a code means a problem somewhere in the whole circuit ;
not just that the major item of that circuit, say in the case of a DTC 43 the KS, itself is actually faulty
