Can bad tps cause rpm creep at idell?

Yes, a faulty throttle position sensor (TPS) can cause RPM creep at idle. If the TPS provides inaccurate readings to the engine control unit (ECU), it may lead to an incorrect air-fuel mixture, causing the engine to run at higher RPMs than intended. This can result in unstable idle and unintended acceleration. Proper diagnostics should be performed to confirm TPS issues and address any underlying causes.
