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.

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.

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).

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).

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.

Yes, not a tech that comes to your home. A real shop who will do a real diagnostic.

I understand but he just took a guess without doing proper diagnostics. I hope he does not do that at his shop as well.

But I am wondering what kind of mechanic he is. I don't think he knows how to set codes. Because I drove it down the street and it just shut off just like if you had switched it off and would not crank until I removed the key from the switch and reinserted it.
