Some Plymouth Breeze owners report experiencing engine power loss and no spark issues after driving, particularly when driving uphill, which may indicate mechanical or electrical malfunctions. These owners often find that the ignition system components, such as the coil, cam position sensor, or crank position sensor, could be the source of the problem. A faulty engine crank sensor (CKP), responsible for measuring engine speed and signaling the engine's computer for spark plug firing, is frequently cited as a common cause of no spark. In severe cases, the failure of the Powertrain Control Module (PCM) may prevent the vehicle from running altogether. To further diagnose these issues, it is recommended that owners check the wiring harness for problems if there is no power to the coil, and if the coil is functioning properly, they should investigate potential issues with the cam and crank position sensors.
