Acura P1302

What P1302 means on a Acura

On Acura vehicles, P1302 is logged when the ECU detects a fault in the ignition / combustion: “Cylinder 2 Misfire”. P1302 is a manufacturer-specific Acura code (the "1" after the letter marks an OEM-defined code), so its meaning applies to Acura and may differ on other makes.

Common causes & symptoms

Typical triggers for a ignition / combustion code like P1302 include faulty or ageing sensors, wiring/connector faults, a clogged or removed component, or a value drifting outside the ECU's expected window. Symptoms range from a check-engine light only, to limp mode, rough running, higher consumption or failed emissions tests.

P1302 and ECU tuning

When a Acura has had hardware changed for off-road/motorsport use (for example a removed DPF or EGR), the related monitor must be disabled in the ECU map or the code re-appears. Softechpro Solutions performs DPF/EGR/AdBlue/DTC off and recalculates the checksum, so codes like P1302 stay cleared after the flash. Genuine faults should always be repaired, not just hidden.
