My '93 has a CEL for code 83, which according to the FSM is an ECT ECU communication error for the ESA1 circuit. From what I've read, when all ECT ECU codes (83, 84, and 85) are thrown together it's usually a bad ECU, but I haven't found much info about code 83 alone. I replaced the ECU with new P/N 89661-60221 just in case, but the same code reappears immediately after each reset.
Has anyone encountered this code before?
Thanks!
