netgabe Posted August 20, 2008 Share Posted August 20, 2008 I need some advice before I put my car in the hands of a mechanic. I have a 1996 ES300 with 130k. Runs great. However, I recently had two codes come up: P1705 (Direct Clutch Speed Sensor Circuit Fault) and P0115 (Engine Coolant Temperature Circuit Malfunction). The car recently started to make loud humming noise as I reached 40 MPH through 60 MPH. Has anyone had experience with this? I'm just trying to stay ahead of the mechanic. I have had no real problems with the car up to this point. I am taking it in this week for timing belt and water pump replacement. (By the way, is this one of those engines that will NOT be damaged if the timing belt breaks?) Thanks in advance for your help! Quote Link to comment Share on other sites More sharing options...
Lexucan Posted August 21, 2008 Share Posted August 21, 2008 I had the ECT sensor replaced in my ES last year as it was sending false readings to the ECU which threw the timing out. I didn't experience any humming noises though. As far as the type of engine is concerned: you have a NON-Interference engine in your '96 ES so it should not sustain any significant damage if the timing belt breaks.
