Quick question on my 2L-TE if anyone has any advice:
I installed my mechanical temp gauge in the my truck last week, expecting a dead gauge in my dash. To my surprise, when I started running the truck I was getting a reading from both the stock and the aftermarket gauges. After a careful look at the wiring diagram for my LJ78, I discovered that there are two senders - one for the gauge and one for the ECU pollution control. Looks like I disconnected the latter.
Does anyone know how critical this reading is to engine operation? The truck seems to run fine and EGT readings are unchanged. I'm mostly concerned about overfueling at low speeds or underfueling at higher speeds.
I'll probably swap the sender back in but I was just curious if anyone had any insight into this issue.
Cheers,
Robin
