P1382 on Acura by model: symptoms, diagnosis and fix
The TEC/Hitachi internal-coil distributor on third-generation Integras is a chronic failure point. Heat from the internal ignition coil degrades the coil, igniter (ICM), and bearings, causing intermittent stalling at operating temperature, hot-restart problems, and dead no-starts. The 1996 Acura Integra has the most overall complaints, with the most-reported problem being distributor failure. This issue can cause difficulty starting the car, stalling, and misfiring. The car has been in the shop because the driver was driving and it just shut off with no warning or light. Come to find out it was the distributor so they changed it.
Common Symptoms
- engine stalls while driving
- hot no-start
- intermittent misfire
- check engine light
- rough idle when warm
- engine cuts out and restarts
How to Fix
Pull DTCs first — codes P1381 (cylinder position sensor) and Code 22 commonly originate inside the distributor. P1381 is the cylinder position sensor code, located inside the distributor. Replace the complete OEM distributor assembly (avoid cheap aftermarket — many fail within months). OBD1 (94-95) and OBD2 (96-99) distributors are not interchangeable. It is worth noting that the distributor plugs are different for each obd generation. So the obd1, and obd2 have different harness plugs. Budget $250-550 for a quality unit installed.

Frequently asked questions
What does P1382 mean on a Acura?
P1382 stands for "Variable Cam Timing Solenoid #1 / 'A' Circuit Malfunction." This is a manufacturer-specific code (commonly Ford and PSA/European applications) indicating an electrical fault in the circuit for variable cam timing solenoid #1, the valve that directs oil pressure to advance or retard camshaft timing. The computer detected that the solenoid circuit is not responding correctly, typically an open, short, or out-of-range signal. Because cam timing affects how the valves open, you may notice rough idle, reduced power, or a check engine light. It is generally an electrical or contamination issue rather than catastrophic engine damage. On Acura it is documented across 1 model: Integra.
What are the most common causes of P1382?
The most common causes of P1382 are: Faulty VCT/VVT solenoid #1, Open or shorted wiring in the solenoid circuit, Corroded or loose solenoid connector, Dirty oil causing the solenoid to stick, Low oil pressure or level, Faulty PCM driver circuit (less common). The specific cause varies by vehicle.
How much does it cost to fix P1382 on a Acura?
Published repair estimates on Acura range from $250 to $600 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
