Diagnostic Aids
If a DTC P0105 cannot be duplicated, the information included in the Freeze Frame/Failure Records data can be useful in diagnosing an intermittent condition.
A TP sensor that is stuck may attempt to auto zero every time the engine runs. An indication if this happens is the TP percentage will be zero percent and TP voltage will be high.
If the condition is intermittent, refer to INTERMITTENTS in TROUBLE SHOOTING NO-CODES - 2.2L SATURN "L" SERIES article.
