In August 2008 with 136,918 miles, my 1996 2.2L VTECH accord’s check engine light (CEL) came on along with major stalling. Made it to AutoZone, and they read the code as P1382. I purchased a remanufactured distributor and had a mechanic replace the distributor. About 500 miles AFTER the distributor was replaced, the CEL came back on. Took it back to AutoZone, and they read the code again as P1382. The car was running normal with no stalling. I did resistance and grounding checks at the distributor’s connector, and all were within spec. I reset the light by removing / replacing the 7.5 Amp radio backup fuse. (Note: the mechanic said the reman distributor was bad and I needed to replace the distributor (again).)
In December 2008 at 139,500 miles, the CEL came on AGAIN (note that I drove the car 2,000 miles with the CEL off). I again reset the CEL by removing / replacing the 7.5 Amp radio backup fuse, but the CEL keeps coming on sometimes after a mile and sometimes after 15 or so miles. The code still reads P1382 when the CEL is on. The car does not stall at all and seems to run fine. However, the CEL coming on and P1382 code is very annoying, and I don’t know what to do. Not sure if replacing the distributor as the mechanic said will solve the problem especially when the wiring looks fine and resistance and grounding checks were within spec. Thanks for any input / insight to this issue.

Hi rjaner,

I have here the diagnostic procedures for the problem.

DTCS P1381 & P1382 - CYLINDER POSITION - (CYP) SENSOR
NOTE: DTC P1381 indicates intermittent interruption in CYP sensor circuit. DTC P1382 indicates no signal in CYP sensor circuit.

1. Perform PCM reset procedure. Start engine. If DTCs P1381 and/or P1382 are not present, system is okay at this time. Failure is intermittent. Check for poor connections or loose wires between CYP connector and PCM connectors. If DTCs P1381 and/or P1382 are present, turn ignition off. Disconnect distributor connector.

2. On Accord (F22B1 engine), measure resistance between sensor terminals No. 4 (CYPP) and No. 5 (CYPM). See Fig. 12 . On Accord (F22B2 engine) and Prelude, measure resistance between sensor terminals No. 2 (CYPP) and No. 4 (CYPM). See Fig. 13 . On Accord, resistance should be 800-1500 ohms. On Prelude, resistance should be 500-1000 ohms.

3. If resistance is not as specified, replace distributor. If resistance is as specified, check for continuity between ground and CYP sensor terminals No. 2 and 4 (Accord F22B1) or terminals No. 4 and 5 (Accord F22B2 and Prelude) individually. See Fig. 12 or Fig. 13 . If continuity exists, replace distributor.

4. If continuity exists, reconnect distributor connector. Disconnect PCM connector "C". See Fig. 4 . Measure resistance between PCM connector terminals C4 and C14 If resistance is not 800-1500 ohms, repair open in appropriate wire(s). See WIRING DIAGRAMS section.

5. If resistance is 800-1500 ohms, check for continuity between ground and PCM connector terminals C4. If continuity exists, repair short in appropriate wire(s). If continuity does not exist, substitute a known-good PCM and recheck. If symptom or problem goes away, replace original PCM.
