2002 Honda CRV variable timng electric control valve

Engine Performance problem
2002 Honda CRV 4 cyl All Wheel Drive Automatic 100000 miles

Dear Sir,
I have a Honda CRV 2002. A few weeks ago I found check engine light on. I cleaned gas cover and the sign went away. Then, 4 days ago, while I was driving at a speed about 40 mph, the car started to choke (appeared as fuel line was cut several times within several seconds) and the check engine light came back on again. Today, I went to an auto mechanic shop and I was told that the engine oil was completely gone. I towed the vehicle to my regular service provider and I was told that the variable timing electric control valve failed then the engine oil leaked out and burned. The logic was that because my car is 180 miles overdue for next service therefore, the variable timing electric control valve was damaged, and then, the damaged value caused oil leak and burn. However, the car ran very well and I never smelled anything. I was not convinced by the provider (180 overdue for oil service damaged the valve). Can you tell me if the valve can cause the oil leak and burned outï¼?



Do you
have the same problem?

Hello Yong

Well, I am sorry to hear of your problems. I have attached a pic showing that the oil does travel through the valve. I would certainly think though you would see oil on the ground or if you were burning oil, blue smoke out the tail. There has to be some evidence of the oil going somewhere.

I don't think not changing the oil for 180 miles though is the problem. I have attached a service bulletin showing that there was a problem with the valves sticking. It had nothing to do with not changing the oil.

I have also attached a TSB concerning the pressure switch.

Last, looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.

I hope this helps in some way

2002 Civic 3-Door and CR-V: MIL Comes On With DTC P0341
(Supersedes 02-041, dated September 24, 2002)

Updated information shown by black bars.


The MIL is on, and DTC P0341 [variable valve timing control (VTC) phase gap] is set.


The VTC control solenoid valve is temporarily stuck or contaminated.




Update the ECM/PCM software using the Honda

Interface Module (HIM), and, if necessary, replace the VTC control solenoid valve.


You will need these tools and equipment items:

Interactive Network (iN) CD (July '02 or later)

iN Workstation

Honda Interface Module (HIM): T/N EQS05A35570

PC Interface Cable (RS232): T/N VET-02002532 This is the same cable you use to connect the PGM Tester to the HONDANET DCS workstation or iN workstation when updating the PGM Tester program card or downloading DTCs to American Honda. The cable is blue with an attached adapter.

AC Adapter (110 VAC/12 VDC Power Supply):
T/N VET-02002426

This is the same adapter used by the PGM Tester. These tools are already at your dealership.


VTC Control Solenoid Valve:P/N 15530-PNB-003, H/C 6921153



In warranty:
The normal warranty applies.

Out of warranty:
Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Parts and Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work.


1. Use the PGM Tester to read and clear the DTC(s).

2. Start the engine, and let it idle.

3. Check the engine idle:

If the engine does not idle smoothly, go to step 4.

If the engine idles smoothly, go to step 5.

4. Replace the VTC control solenoid valve. Refer to page 11-127 of the 2002 Civic Si Service Manual or page 11-133 of the 2002 CR-V Service Manual.

5. Make sure you have the Interactive Network (iN) CD (July '02 or later) loaded into your iN master terminal. If not, load the CD using the instructions that come with it.

TITLE: Replace VTEC Oil Pressure Switch for DTC P2646, P2647

APPLIES TO: 03-05 Accord 4-cylinder

02-05 CR-V


Got a vehicle in your shop with either of these DTCs?- DTC P2646 (VTEC oil pressure switch circuit low voltage)
- DTC P2647 (VTEC oil pressure switch circuit high voltage)
Replacing the VTEC oil pressure switch usually fixes the problem. If it doesn't, then press on with normal troubleshooting.
