Chrysler Esx C1396 Engine Trouble Code
What is Chrysler Esx C1396?
When Chrysler Esx C1396 code appears, first check your gas cap. Pull over safely, ensure it is tight, and inspect for cracks. A loose or damaged gas cap affects fuel-system pressure and emissions. A replacement cap costs about $3–$10. This simple fix can resolve the code and improve fuel economy.
C1396 on the Chrysler Esx
Chrysler Esx models produced in the mid-cycle refresh years show a statistical uptick in C1396 occurrences linked to the variable valve timing (VVT) actuator. A sludge deposit in the oil galleries feeding the actuator is the leading suspect.

C1396 Code Structure
Understanding what each digit means in the C1396 chassis trouble code:
| C | 1 | 3 | 9 | 6 |
|---|---|---|---|---|
| Chassis Code | Fuel And Air Metering | Throttle/Pedal Position Sensor/Switch A Circuit Intermittent | Crankshaft Position Sensor A Circuit Malfunction | Ignition Coil A Primary/Secondary Circuit Malfunction |
How to Fix Chrysler Esx C1396
Diagnostic Steps:
Oxygen sensors measure exhaust gas oxygen content to optimise air-fuel ratio. This optimisation improves fuel economy and reduces emissions. Sensors degrade over time and require periodic replacement.
Repair Solution:
VSS concerns may stem from noisy input signals caused by RFI/EMI from ignition wires, charging circuits, or aftermarket equipment. Verify VSS reads 0 mph when transmission is in Park.
Technical Notes:
C1396 DTC specifically relates to camshaft timing. When cam timing is over-retarded, the check-engine light illuminates and this code sets. Verify VCT solenoid operation and check for contamination.
Chrysler Esx C1396 Repair Cost
Crankshaft reluctor ring inspection and replacement on the Chrysler Esx is a major service item costing $600–$1,100. Given the labour required to access the component, it is advisable to replace the rear crankshaft seal and crankshaft position sensor simultaneously while the area is open.
C1396 Description
C1396 engine trouble code is related to Ignition Coil A Primary/Secondary Circuit Malfunction.
Main Cause
The primary reason for C1396 OBD-II Engine Trouble Code is: Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.
Common C1396 Misdiagnosis on the Chrysler Esx
Replacing the PCM/ECU on the Chrysler Esx for a persistent C1396 is a last-resort action that is often performed prematurely. Statistically, less than 2% of C1396 faults on this platform originate in the ECU; wiring, sensors, and mechanical causes account for the remainder.
DIY Repair Guide: C1396 on Chrysler Esx
Battery terminal cleaning on the Chrysler Esx is a 5-minute job that resolves a surprising number of C1396 intermittents. Use a wire brush and a bicarbonate of soda solution to clean corrosion, then apply a thin coat of petroleum jelly to the terminals after refitting.
Preventing C1396 on the Chrysler Esx
For Chrysler Esx owners in high-humidity climates, applying electrical contact cleaner and dielectric grease to the ECU connector pins every two years prevents the corrosion-related signal errors that register as C1396.
Frequently Asked Questions — Chrysler Esx C1396
A: Yes. A weak battery causes voltage drop during cranking that confuses the ECU and can store a range of fault codes. Always rule out battery and charging system health before diagnosing sensor-related codes.
