DTC P2184:00: Notes

DTC P2184:00	ECT sensor No.2 circuit low input
DETECTION CONDITION	The PCM monitors the ECT sensor No.2 signal. If the PCM detects that the ECT sensor No.2 voltage is below 0.11 V for 5 s , the PCM determines that the ECT sensor No.2 circuit has a malfunction. Diagnostic support note This is a continuous monitor (engine cooling system). The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	ECT sensor No.2 connector or terminals malfunction ECT sensor No.2 malfunction Short to ground in wiring harness between ECT sensor No.2 terminal A and PCM terminal 1Y PCM connector or terminals malfunction ECT sensor No.2 signal circuit and ground circuit are shorted to each other PCM malfunction
