Use the Forum Jump below to find the How-to tab for all the info about the ects. All S-series up to '01 have the original faulty plastic coolant sensor and need replacing whether or not they're cracked. The temp gauge needle reflecting coolant temps changing as the engine warms up eliminates it but not completely. This would leave the transmission temperature sensor as the other faulty sensor.Įither the low coolant sensor or transmission temperature sensor is faulty. Since the ects does double duty, input to the pcm as well as temperature display, a good display showing the needle movement as the engine warms up eliminates a faulty ects. If not, then either the ects or transmission temperature sensor is faulty. Try it and see if the low coolant light turns off turning off the light means replacing the coolant reservoir. Disconnecting the coolant sensor and shorting the two pins on the connector would be as if the float ring were above the low level line in the reservoir.

During engine start-up the engine coolant temp/low coolant/auto trans fluid temp telltale indicator lamp is turned ON by the PCM for a bulb check.īased on the descriptions above, a low coolant level (float below minimum coolant level) opens the coolant switch. When either of the sensors signals a temperature that is above the specified range or the coolant level switch opens due to a low coolant level in the coolant surge tank, the PCM will ground circuit 35 and turns the engine coolant temp/low coolant/auto trans fluid temp telltale indicator lamp ON to inform the operator of the vehicle that one of the above conditions has occurred. The PCM monitors the inputs of the ECT sensor, transmission fluid temperature sensor and the coolant level switch to determine if the ECT, automatic transmission fluid temperature and coolant level are within normal operating ranges. Also, a description from the FSM is reprinted here.Įngine Coolant Temp/Low Coolant/Auto Trans Fluid Temp Telltale The float would contain a small magnet and the sealed reed switch permanently positioned in a plastic column for the float ring to allow movement up and down. Anyway, the following is a brief schematic of the coolant sensor and I presume the symbol represents a magnetic reed switch that simply operates on magnetic attraction to open or close a set of contacts in a sealed unit. A coolant sensor is a coolant sensor or at least that's what I see. Thank you for your understanding.I couldn't find the electrical symbol interpretation for the coolant level sensor in the '99 FSM or '03 元00 FSM. If you have any questions, send us a modmail.
