Cylinder Position (CYP) Sensor 1 No Signal

Enter your vehicle for a personalized diagnosis for code P1382
The P1382 code is a Honda-specific code indicating a complete loss of signal from the Cylinder Position (CYP) Sensor 1. The CYP sensor identifies which cylinder is at its firing position so the ECM can control sequential fuel injection. Without this signal, the ECM cannot determine which cylinder to inject fuel into, which typically means the engine will not run or will stall and refuse to restart.
This is a more severe condition than P1381 (intermittent interruption). If you receive this code, your engine has likely already stalled or failed to start. The CYP sensor is part of the distributor assembly on most Honda engines from the mid-1990s to early 2000s, so it cannot be replaced as a standalone part. The entire distributor must be replaced.
Before purchasing a new distributor, verify the problem isn't simply a disconnected or broken wire. Check the connector at the distributor for obvious damage. If the wiring is intact, the distributor assembly is the most likely culprit. Aftermarket Honda distributors are readily available and typically cost $80–$200. Installation requires setting the engine to TDC, removing the old distributor, installing the new one, and verifying ignition timing — a task most intermediate DIYers can handle with a repair manual.
Severity
Symptoms
- •Engine will not start or dies immediately after starting
- •Complete engine stall while driving
- •Check Engine light illuminated
- •Engine cranks but will not fire
- •Loss of fuel injection sequencing
- •Possible rough running before complete failure
Likely Causes
The Cylinder Position sensor has completely failed and produces no output signal, preventing the ECM from determining cylinder position.
A fully severed wire or disconnected connector eliminates the CYP sensor signal to the ECM.
Internal mechanical failure of the distributor — bearing seizure, shaft damage, or rotor failure — can destroy CYP sensor function.
Rarely, the ECM circuit that processes the CYP sensor signal can fail, though sensor and wiring problems are far more likely.
