According to the FSM the "acceptable" range for resistance on the EGR sensor is between 570k - 700k ohms, which indicates ~122 deg FThe minimum is 80k-100k ohms which is ~212 deg FThe max is 7.9M-9.7M ohms which is ~32 deg FdeviousKA wrote:Im not exactly sure of what resistance is needed to trick the circuit, but there is an easy way to find out.
Get the car to full operating temp with the EGR hooked up and make sure no codes are thrown. While still at full temperature, unplug the EGR temp connection and simply measure the resistance.
1/4 watt resistor is fine.
The problem most are probably having is matching the resistance of the sensor when cold. The ecu begins reading the voltage only after a certain coolant temperature, so with this configuration it would be sensing as cold when it should be at full temp, throwing a CEL.
So i personally would use a 600k ohm resistor and go from there...
