P0107 Quick Answer
P0107 indicates: Manifold Absolute Pressure Sensor Circuit Low. Read freeze frame data and check fuel trims (STFT/LTFT) before any component testing — the load conditions captured at the moment of fault often pinpoint the failing system.
What Does P0107 Mean on a Chrysler 300C?
The Chrysler 300C LX platform stores P0107 when the affected module detects manifold absolute pressure sensor circuit low. This code is logged by the controller responsible for the engine performance system on this vehicle. The applicable model years cover the LX platform production run (2005-2010 for the 300C; the same code definitions apply to the related Charger, Magnum, and Challenger LX-platform vehicles when fitted with the same module).
Symptoms
Symptoms vary with the specific subsystem affected, but commonly include one or more of:
- Warning light or indicator on the instrument cluster
- Reduced functionality of the affected system (engine performance)
- Loss of related convenience or safety features
- Possible co-codes from connected modules on the CAN bus
Common Causes
- Fault in the named component, sensor, or actuator circuit
- Open or shorted wiring in the affected circuit
- Connector corrosion, water ingress, or backed-out terminal
- Loss of supply voltage or ground at the affected device
- Module internal fault (rare — verify wiring and supplies first)
Diagnostic Approach
For P0107 on the Chrysler 300C LX you’ll need a bidirectional scan tool capable of reading PCM live data and freeze frame, a digital multimeter, and access to the LX-platform powertrain wiring diagram.
- Read freeze frame data and check fuel trims (STFT/LTFT) before any component testing — the load conditions captured at the moment of fault often pinpoint the failing system.
- Verify the fault is current (active) and not just stored history. Some 300C LX modules retain history codes for many cycles after the underlying issue is resolved.
- Inspect the connector at the device named in the code description. The LX-platform harnesses suffer from terminal-tension loss in flex zones — wiggle-test the connector while monitoring live data.
- Measure supply voltage and ground integrity at the affected device with the engine running.
- If supplies are good and the connector is sound, isolate the device with a known-good substitute or a load resistor matching the expected impedance.
- Clear the code, drive the vehicle through one or two cycles to confirm the fault does not return.
Possible Fixes
- Replace the failed device named in the code description
- Repair open or shorted wiring
- Connector pin-tension or pigtail repair
- Module replacement and programming if the module itself is faulty
Can I Still Drive With P0107?
Drivability impact depends on the affected subsystem. ENGINE PERFORMANCE faults that affect a primary safety system (brakes, restraints, steering) should be repaired before further driving. Comfort or convenience-system faults can usually be deferred briefly without immediate safety risk, but should still be addressed to prevent the fault from cascading into related codes.
How Serious Is This Code?
P0107 is a ENGINE PERFORMANCE code on the Chrysler 300C LX. Address based on subsystem priority: brake, airbag, and steering codes are urgent; comfort, lighting, and audio codes are moderate priority. Network-communication codes can hide other faults and should be diagnosed early in the troubleshooting flow.
FAQ
Will P0107 clear itself on a Chrysler 300C?
If the underlying fault was a momentary glitch — for example a brief connector dropout or a one-time low-voltage event — the P0107 may clear after a few drive cycles. Persistent root causes (failed device, broken wire, corroded terminal) will keep the fault active until the affected component is repaired on the Chrysler 300C.
Can I drive my Chrysler 300C with P0107 active?
It depends which subsystem is affected. If the P0107 is in a primary safety system (brakes, restraints, steering, air suspension), the Chrysler 300C should be driven only to a workshop. Comfort, lighting, and audio faults are lower priority but still worth addressing — the Chrysler 300C’s CAN architecture means a single unresolved code can mask others.
How much does it cost to fix P0107 on a Chrysler 300C?
Repair cost depends on the named device. On the Chrysler 300C, simple connector or wiring repairs typically run $80-200 in shop labour. Sensor replacements run $120-450 including parts and diagnostic time. Module replacement (when the affected control module itself has failed) is the most expensive path at $400-1,200 depending on whether the new module needs programming.

What does the official Chrysler 300C service definition say about P0107?
Per the factory service information, P0107 is defined as: Manifold Absolute Pressure Sensor Circuit Low. The diagnostic procedure is in the Chrysler 300C service-manual chapter for the affected module.
