P1353 · ChryslerIC Output High Pulse Detected When Grounded Cyl 3

Q: What does code P1353 mean?

IC Output High Pulse Detected When Grounded Cyl 3. P1353 on Chrysler vehicles means the engine controller detected an unexpected high voltage pulse on the ignition coil output circuit for cylinder 3 when that circuit was commanded to ground. The computer tried to fire the coil by pulling the control wire low, but the circuit stayed high or pulsed high when it should not have, so the cylinder may not have fired correctly.

Symptoms you may notice

Check engine light illuminated, often with no other noticeable symptoms
Rough idle or misfire sensation, especially when the engine is cold or under light load
Hesitation or stumble during acceleration from a stop
Slightly reduced fuel economy if the misfire is frequent
In some cases, a flashing check engine light if the misfire is severe enough to damage the catalytic converter

Common causes, most likely first

Faulty ignition coil for cylinder 3 with an internal short or open in the primary winding
Damaged or chafed wiring in the coil control circuit between the powertrain control module and the coil
Corroded or loose connector terminals at the cylinder 3 ignition coil
Failed ignition coil driver inside the powertrain control module
Spark plug fouled or worn, causing abnormal coil feedback
Aftermarket alarm or remote start wiring tapped into the coil circuit

How to diagnose and fix it

Scan all modules and record freeze-frame data to confirm the code is current and not history
Inspect the cylinder 3 ignition coil connector and wiring for corrosion, chafing, or loose pins
Swap the cylinder 3 ignition coil with another cylinder and see if the code follows the coil
Measure resistance of the cylinder 3 coil primary and secondary windings and compare to specification
Back-probe the coil control wire with a lab scope to check for a clean ground pulse from the powertrain control module
Check for continuity and short-to-voltage on the coil control circuit between the powertrain control module and the coil
If the circuit and coil test good, diagnose the powertrain control module driver or replace the module as needed

What the coil control pulse really tells you

A code P1353 can set intermittently from a coil that only breaks down when hot, so a cold resistance check may pass and mislead you.
The powertrain control module expects to see the control wire pulled low during the dwell period, and any voltage above its threshold triggers this code even if the coil still fires.
Aftermarket remote start or alarm installers sometimes tap the coil control wire for a tach signal, and that added load can cause a high pulse code.
A worn spark plug with an excessive gap can raise the coil's firing voltage and feed back into the primary circuit, setting this code without a bad coil.
Do not replace the powertrain control module until you have scoped the control wire at the coil, because a chafed harness shorting to voltage mimics a failed driver.

Can I keep driving with P1353?

You can usually drive the vehicle short distances if the only symptom is a steady check engine light, but avoid heavy acceleration and towing until the misfire is repaired. If the check engine light flashes, stop driving and repair the fault immediately to prevent catalytic converter damage.
