2013 Chrysler 200 2.4L: P2305 and P0118 Fault Codes - Car Won't Start

Model: Chrysler 200 Fault Code: P0118 Posted: 2021-03-08 17:24

My 2013 Chrysler 200 with a 2.4L engine and 6-speed transmission will not start, despite having two diagnostic trouble codes: P2305 and P0118. The vehicle cranks but fails to ignite. I've already replaced the coolant temperature sensor (a thermistor) with a used unit, and both thermostats were replaced with new ones. After running the engine briefly, it shut off unexpectedly when I walked away. I suspect a wiring or connection issue in the CTS circuit, as this sensor plays a critical role in engine starting. The P0118 code—related to intake air temperature—may be linked, but I'm unsure of the exact cause. I've cleared the codes and returned to check if they reappear. I also tried pressing the gas pedal during cranking with no response. A spark test on all four coils shows inconsistent results. I suspect a faulty PCM or internal circuit damage, especially given that the previous replacement part may have caused issues. I now believe the PCM has burn spots on the driver's side circuit board. If the PCM is damaged, replacing it could cause further problems unless the root cause of the failure is identified first.

Did both P2305 and P0118 appear simultaneously? What is the engine size?

Yes, it's a 2.4L engine.

I experienced fan activation issues and replaced the coolant temperature sensor with a used unit, then installed new thermostats. After running the car briefly, it shut off when I left. The vehicle cranks but won't start.

Check for spark at all four coils while cranking using a spark tester connected to battery ground. Inspect coil harnesses for damage. Try starting with the gas pedal partially depressed, then fully pressed. A misaligned coolant temperature sensor (CTS) can cause starting issues. Clear the codes with a scan tool and monitor if they return after cranking. Be cautious—some testing procedures may inadvertently short or damage PCM components. I'll review the Mitchell On Demand wiring diagrams later. Testing requires proper tools like a multimeter or test light.

The replaced sensor is the coolant temperature sensor (a thermistor), which is vital for starting. A defective used part, poor connection, or faulty wiring in the CTS circuit could be the issue. I don't know why both codes triggered—circuit diagnostics are needed. Clear the codes and monitor if they return. Try pressing the gas pedal slightly during cranking to help ignition; full throttle may flood the engine and prevent starting.

I tried pressing the gas pedal, but there was no movement or sound—no response at all.

I cleared the codes and returned to check for recurrence.

The issue appears to be related to a single underlying cause, not multiple separate faults.

The problem may stem from the coolant temperature sensor when it reaches operating temperature.

The coolant temperature sensor and intake air temperature sensor are both thermistors. Do you understand what a thermistor is? Do you have access to a scan tool capable of reading live data streams? Are there consistent spark signals at all coils? Ensure the coil-on-plug system is correctly installed—avoid using parts from junkyards.

The coolant temperature sensor and intake air temperature sensor are both thermistors. Do you know what a thermistor is? Do you have a scan tool capable of reading data stream? Do you have good spark to all coils? Coil on plug correct? I Wouldn't use junk yard electronic parts.

I discovered burn spots on the PCM board during inspection.

Where exactly are the burn spots located on the PCM? On the connector or on the circuit board itself?

On the driver's side of the PCM unit.

I meant the location on the connector, not the physical position. The PCM circuit board is enclosed in a metal case. If the PCM is damaged, replacing it may cause further issues—especially if a new programmed PCM is installed, as it could be destroyed during installation. Unless something was done during previous repairs that caused the damage.
