i have a pr4 ecu and it is flashing 3manifold absolute pressure 8 tdc position and 13 atmospheric pressure what do i need to do to fix these codes ???

 

Year/make/model?

 

Manuals can be found at www.hondatech.info run the diag for each code. In general its ether a sensor, ecu or wiring problem.

Map and tp sensor connectors can easily be mixed they also share the same 5v ref and ground iirc. The distributor code stands alone and is probably unrelated to the two other codes.
