jyeager Posted February 25, 2019 Share Posted February 25, 2019 That 2nd sensor looks to be the ambient air temperature sensor. Is that in front of the battery, toward the vehicle's grill? I also can't quite get my bearings on the first picture. What side of the engine? If I had to guess, I think I'm seeing it inside an exhaust runner? Or is that an intake runner? But it seems to be integrated with the piping...which would lead me to believe it's the EGR system or the AIR system. EGR = exhaust gas recirculation which is used to improve emissions in some situations AIR = air injection system to treat exhaust gasses, also for emissions Link to comment Share on other sites More sharing options...
Slartibartfast Posted February 25, 2019 Share Posted February 25, 2019 (edited) I'm pretty sure that first one's a fuel injector. My '93 has a dropper resistor for the trans in a similar location to the thing in the second pic, so I'm betting that's what you're looking at there. The service manual should show both units, though it may take some trial and error to find the right diagram.

adamzan Posted February 26, 2019 Share Posted February 26, 2019 That looks exactly like another fuel injector plug. Is it just sitting there or ? Link to comment Share on other sites More sharing options...
