DTC P0537:00: Notes

DTC P0537:00	Evaporator temperature sensor circuit low input
DETECTION CONDITION	If the input voltage is less than 0.08 V for 16 s or more , the PCM determines that the evaporator temperature sensor circuit has a malfunction. Diagnostic support note This is a continuous monitor (other). The MIL does not illuminate. FREEZE FRAME DATA (Mode 2)/Snapshot data is not available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Evaporator temperature sensor connector or terminals malfunction Evaporator temperature sensor malfunction Short to ground in wiring harness between evaporator temperature sensor terminal B and PCM terminal 1AW PCM connector or terminals malfunction Evaporator temperature sensor signal circuit and ground circuit are shorted to each other PCM malfunction
