How to Fix Chrysler Firepower P1260
Diagnostic Steps:
Regarding P1260, carefully inspect the wire harness near the intake manifold bracket, best accessed from below near the oil filter. Look for chafing, pinching, or damaged insulation.
Repair Solution:
Firing order is engineered to minimise vibration. Altering firing order results in mistimed ignition and poor engine operation. Consult vehicle-specific repair manual for correct firing order.
Technical Notes:
P1260 on electronically controlled automatic transmissions relates to shift solenoid operation. The solenoid actuates hydraulic circuits controlling clutches or bands for gear changes.
Chrysler Firepower P1260 Repair Cost
On the Chrysler Firepower, secondary air injection pump replacement for a P1260 code runs $350–$600. Because the pump is only active during cold starts, symptoms are easily missed. Requesting a cold-start emissions test at the workshop will confirm whether the pump is operating.

Main Cause
The primary reason for P1260 OBD-II Engine Trouble Code is: Manifold Absolute Pressure/Barometric Pressure Circuit High Input.
Common P1260 Misdiagnosis on the Chrysler Firepower
Some Chrysler Firepower models have a known software bug where the PCM flags P1260 after battery disconnection and reconnect. Always perform an ECU adaptation reset and drive cycle before ordering any parts following battery work.
DIY Repair Guide: P1260 on Chrysler Firepower
Replacing the oxygen sensor on the Chrysler Firepower requires an O2 sensor socket (22mm or 7/8") and penetrating oil applied 24 hours in advance. On vehicles over five years old, the sensor threads often corrode into the bung; heat from a propane torch (briefly applied) is usually sufficient to free them.
Preventing P1260 on the Chrysler Firepower
The Chrysler Firepower coolant temperature sensor plays a role in fuel enrichment during warm-up. Replacing it as a precaution at 80,000 miles ($25–$40 DIY) prevents the faulty cold-start enrichment that can lead to P1260.
