Check Engine Light
Hey wassup i have a 91 ef and my check engine light is on.. i read the code on the ecu and it blinks 6 times. ever since the light came on my gas milage has been sucking. i know in theowners manual says 6 blinks is temperature gauge and something else i cant remember but i tried reseting the ecu by disconnecting my battery for like 20 minutes but its still there. my book says take car t dealership but nahhh.. so what could it be or what can i do ? thanks

Re: Check Engine Light
ok, if code 6 is a temp issue, what is the temp gauge reporting? when was the last time you flushed the coolant? or changed the thermostat?

Re: Check Engine Light
Code 6 - Coolant Temp Sensor. Check to make sure it is plugged in and the wire isn't broken. If all is good, they are like 20$ at Auto Zone.

Re: Check Engine Light
code 6 is for the temperature sensor (TW) for the ECU, not the gauge - gauge sensor doesn't give a CEL and a code - TW sensor affects injector timing and duration, ignition timing, idle control, etc. - TW sensor is located on the end of the head below the distributor - has a 2-wire connector with red/white and green/white wires - either the sensor is bad or you have a problem with the wires or connector
