Jeep Code P2173 is a diagnostic code that indicates a problem with the Throttle Actuator Control System of a Jeep vehicle. This code is triggered when the Powertrain Control Module (PCM) detects a gradual long term increase in the difference between the actual Map Pressure sense and calculated Map Sensor value, beyond the calibrated adaptive limit. This can be caused by a number of different issues related to vacuum leaks, exhaust system restrictions, internal engine mechanical components, and resistance in the 5-volt supply and MAP signal circuits. Understanding the causes and solutions to Jeep Code P2173 can help drivers to diagnose and repair their vehicle quickly and safely.
Causes and Solutions to Jeep Code P2173
| Cause | Solution |
|---|---|
| Vacuum Leak | Check for tears or holes in the vacuum lines and replace any damaged lines. |
| Restriction in Exhaust System | Inspect the exhaust system for obstructions such as broken catalytic converters, clogged mufflers, or kinked exhaust pipes. |
| Internal Engine Mechanical Components | Check for worn or damaged internal engine components, such as valves, piston rings, or cylinder heads. |
| Resistance in 5-Volt Supply Circuit | Check the wiring harness and repair or replace any damaged or corroded wires. |
