This problem was repaired check engine light went out after repair, but after a few minutes it came back on. Had it rechecked and the results said the camshaft position needs to be replaced again. When I took it to be inspected The report said MIL status he Malfunction Lamp Is Commanded On.

Good afternoon,

The repair was unsuccessful. Whatever they did was not the correct repair.

Codes rarely identify bad parts, just failed systems. Diagnostics have to be done to determine the failure.

What was the exact code that was set?

I don't know about codes. I had this repair made by a come to your home mechanic. What he did or what codes he used I have no idea. What does this inspection report mean by The Malfunction indicator lamp is commanded On?

That means a code is stored in the module. I need that code to help you.

You can go to a parts store and have them read it for free. Once I know that code, I can get the information on what needs to be checked.

Okay, Let me check. That code indicates a wiring issue.

Roy

Possibilities

P0365
Descriptor
Probable Causes
Camshaft Position (CMP) Sensor B
Camshaft Position (CMP) Sensor B Sensor Wires Shorted
Camshaft Position (CMP) Sensor B Wires Open
Poor Connections or Loose Terminals At Camshaft Position (CMP) Sensor B and At Powertrain Control Module (PCM)
Powertrain Control Module (PCM)

Flow chart that needs to be followed

DTC P0365: CMP Sensor B No Signal

1. Reset the PCM.
2. Start the engine.

Is DTC P0340, P0341, P0365, P0366 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the CMP sensor A/B and at the PCM.

3. Turn the ignition switch OFF.
4. Disconnect the CMP sensor A/B 4P connector.

ImageOpen In New TabZoom/Print

5. Measure resistance between the terminals of the indicated sensor (see table).

Is there 1,850 - 2,450 Ohms?

YES - Go to step 6.

NO - Replace the CMP sensor A/B.

ImageOpen In New TabZoom/Print

6. Check for continuity to body ground on both terminals of the indicated sensor individually.

Is there continuity?

YES - Replace the CMP sensor A/B.

NO - Go to step 7.

7. Reconnect the CMP sensor A/B 4P connector.
8. Disconnect PCM connector C (31P).

ImageOpen In New TabZoom/Print

9. Measure resistance between the terminals of the indicated sensor on the PCM connector (see table).

Is there 1,850 - 2,450 Ohms?

YES - Go to step 10.

NO - Repair open in the indicated sensor wires (see table).

ImageOpen In New TabZoom/Print

10. Check for continuity between body ground and PCM connector terminals C20 and/or C29 individually.

Is there continuity?

YES - Repair short in the indicated sensor wires.

NO - Substitute a known-good PCM and recheck. If the symptom/indication goes away, replace the original PCM.

Replace cam sensor ran once and no spark when tried to start again. Just to give you a bit more info, a cam sensor is usually used for fuel monitoring by the ecm, check on your rmp signal when cranking. On hondas I find crank sensors to be a common fault when no spark issues arise. Any codes?
