2011 Chrysler 200 P0121 and P2135 Codes: Same Root Cause or Separate Repairs?

I recently encountered two diagnostic trouble codes on my 2011 Chrysler 200: P0121 and P2130. I'm trying to determine whether these codes point to the same underlying issue or if both require separate component replacements. Specifically, for the 3.6L engine, P0121 indicates a throttle position sensor (TPS) 1 performance problem, while P2135 points to a correlation issue between TPS 1 and TPS 2. I believe the root cause may be related to wiring or voltage inconsistencies in the TPS 1 circuit. Can anyone confirm if these codes are linked and what steps should be taken for diagnosis and repair?

Which engine model? For the 3.6L engine: - P0121: Throttle Position Sensor 1 Performance Issue - P2135: Throttle Position Sensor 1/2 Correlation Issue The issue likely stems from wiring or voltage problems in the TPS 1 circuit. Check for loose connections, corrosion, and proper signal voltages to diagnose accurately.
