2004 Dodge Ram 2500 Diesel P2127 Code: Throttle Position Sensor Circuit Low - Diagnosis and Repair

Model: 2004 Dodge Ram 2500 Diesel Fault Code: P2127 Posted: 2015-06-21 14:51

I've been experiencing battery issues, so I replaced both batteries. After the replacement, a P2127 diagnostic code appeared on my 2004 Dodge Ram 2500 Diesel (Throttle/Pedal Position Sensor Switch E Circuit Low). I'm wondering if this indicates a faulty Throttle Position Sensor (TPS) or whether it could be caused by another electrical issue. Any suggestions on how to diagnose and fix the P2127 code? Is replacing the TPS necessary, or are there other potential causes?
