Q: What does code P1700 mean?

TCM Throttle Position Sensor Circuit Fault. P1700 on a Suzuki means the Transmission Control Module (TCM) has detected an electrical fault in the throttle position signal circuit it monitors. The TCM compares the throttle position sensor (TPS) voltage against expected values and sets this code when the signal is out of range, intermittent, or missing entirely. This affects shift quality because the TCM uses throttle position to decide shift points and line pressure.
