4AGZE: ECU pinouts
Posted: Mon Aug 10, 2009 1:59 pm
the California emissions specific EGR temp sensor is a 2 wire sensor: 1 wire connects to the THG pinout while wire 2 connects to the E2(along with other sensors, etc...) pinout. the ECU E1 pinout is then the external ground.
This is something to be aware of when you're looking to replace or convert to a GZE setup.
it'll make things easier keeping a California emissions ECU (89661-17130) matched with its corresponding harness. non-California emissions GZE setups/harnesses should stick with non-California ECUs (89661-17230). Keep in mind neither harnesses are plug and play with any JDM MAP based/DLI GZE ECUs.
hope this helps clear things up for everyone.
