DTC P0098: Notes

DTC P0098 [L3 WITH TC] DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0098	Boost air temperature sensor circuit high
DETECTION CONDITION	If the PCM detects that the boost air temperature sensor voltage is 4.96 V or more, the PCM determines that the boost air temperature sensor circuit voltage is high. Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA is available. DTCs are stored in the PCM memory.
POSSIBLE CAUSE	Boost air temperature sensor malfunction Open circuit between MAP/boost air temperature sensor terminal A and PCM terminal 2AV Open circuit between MAP/boost air temperature sensor terminal B and PCM terminal 2N Short to the power circuit between MAP/boost air temperature sensor terminal A and PCM terminal 2AV Short to the power circuit between MAP/boost air temperature sensor terminal B and PCM terminal 2N Connector or terminal malfunction PCM malfunction
