2003 Dodge Ram 1500 Q&A
2003 Dodge Ram 1500 Question: I need to replace my Electronic Throttle Control.
My truck threw a P2106 P2108 fault code. I lost all power. I had a mobile mechanic come out to verify the code. Which was the ETC. The butterfly on the throttle body does not open fully when you press on the accelerator ( Gas Pedal ) He determined it needed to be replaced. I ordered a new one from the dealers, It will be in tomorrow. My question is, Do I need to get my truck reprogrammed or re Mapped? It only required the removal of 4 bolts and to reconnect the electronic module. - mke
That "mobile mechanic" has misdiagnosed the problem incorrectly. Here is the solution. Vehicle Application: 2003 Dodge Ram 1500 Pickup 5.7L, Vin D, Eng Cfg V8 2003 Dodge Ram 2500 Pickup 5.7L, GAS, Vin D, Eng Cfg V8, USA/Canada Customer Concern: The check engine light is on. It has trouble codes P2106 and P2108. Tests/Procedures: 1. Check the Manifold Absolute Pressure (MAP) sensor voltage. Key on engine off it should be approximately 4.5 volts, idling in the 1 volt range and go over 4 volts at a snap throttle. 2. Check the Throttle Position Sensor (TPS) voltage in the pedal follower test with the scan tool. At closed throttle TPS #1 should be approximately 0.5 volt and at Wide Open Throttle (WOT) over 4 volts. TPS #2 should read 4.5 volts closed and 0.5 volt at WOT. 3. Check into TSB #18-013-03 for Powertrain Control Module (PCM) reflash. Potential Causes: Restricted AIR Manifold Absolute Pressure (MAP) Sensor Powertrain Control Module (PCM) Throttle Position Sensor (TPS) Wiring Harness Tech Tips: TSB 18-013-03. Diagnostic Codes: P2106, P2108 If you want a copy of that TSB I can email it to you. 239-220-5869 - Visitor
