Kia Soul P0707 Diagnostic: Reverse and One Forward Gear with Hard Shifting
My Kia Soul is displaying fault code P0707. The vehicle only engages reverse and one forward gear, and shifts hard into all gears. The gear linkage moves freely, indicating mechanical movement is not the issue. I'm experiencing difficulty in achieving smooth gear transitions. Fault Code P0707 (Transmission Range Sensor A Circuit Malfunction) triggers under the following conditions: - Engine state: "RUN" - Battery voltage: 11V ≤ Voltage ≤ 16V - Throttle Position Sensor (TPS): ≥ 3% threshold value - No signal detected from the transmission range sensor - Diagnostic time exceeds 30 seconds - Fail-safe recognition: When P-D, R-D, or D-R shift is detected, it registers as N-D or N-R even if 'N' position is not detected. If sports mode is enabled without P/R/N/D signals, it is recognized as sports mode (DTC not set). Possible causes include: • Open or short circuit in the transmission range sensor wiring • Faulty shift cable adjustment • Defective inhibitor switch or manual control lever position adjustment • Malfunctioning transmission range switch (TRANSAXLE RANGE SWITCH) • Electronic fault in the TCM (Transmission Control Module) or PCM
Trouble Code Conditions: Enable Conditions: Engine state = "RUN", Battery Voltage between 11V and 16V, TPS ≥ 3% threshold value. No signal detected from the sensor. Diagnostic time exceeds 30 seconds. Fail Safe Recognition: When P-D or R-D or D-R shift is detected, it registers as N-D or N-R even if 'N' signal is not present. If sports mode is enabled without P/R/N/D signals, it is recognized as sports mode (DTC not set). Possible Causes: • Open or short circuit in the transmission range sensor wiring • Faulty shift cable adjustment • Defective inhibitor switch and manual control lever position adjustment • Faulty TRANSAXLE RANGE SWITCH • Faulty TCM (Transmission Control Module) or PCM
