1997 Acura RL 3.5L, how many spark plug control detection modules are in a car? I got the engine codes P1316-P1319

Answer 1

You only have one sparkplug voltage detection module that controls both banks. it location is on the passenger upper firewall section it is a grey box. What set this code is one thing a failed unit, Where is what will not set this code,  wrong  sparkplugs ,broken s parkplug, skewd ignition module, Here is what will set this code,sparkplug detection module  has  bad connection to the detection module, The sparkplug detection moduel itself.
