Honda 2005 crv engine code P0780 what does that mean?

SOURCE: P1457 - Honda Civic 2005 LX

this car come with tree diferent engines the answer i'm going to give you is for a 1.7 engine sohc that codes means you have a leak on the evaporative system this system monitor the vapors from fuel tank this code some time might appear for filling the fuel tank with car runing i recomend you to clear code and make sure the fuel cap is not loose because there is a fuel pressure sensor in the tank and if the sensor don't read the right pressure then it will set the code

SOURCE: 2000 Accordlx eng. light on and drive blinks yellow code p0780?

po780 is a trans hydrolic systen code
could be a shift solinoid gone bad
have an experienced mechanic replace the lock-up controlle solenoid control solenoid valve/shift controlle solenoid valve "A" assembley
and the A\T clutch pressure control solenoid valve "A"/"B" assembley
start with these two parts farily inexpensive if this doesnt solve the problem then the trans needs to be replaced really expensive
both of these parts are located on the out side of the trans
rank my solution

P2647 VTEC Oil Pressure Switch Circuit High Voltage - With Automatic Transmission Basicallly the sensor has gone bad or an oil passage has become blocked.

**. Locate the Variable Timing Electronic Control (VTEC) pressure switch on the end of the cylinder head. Honda has had problems with the VTEC oil pressure switch, there is an updated part number for the vehicle (37250-PNE-G01). On this vehicle the VTEC oil pressure switch can fail at any RPM.
2. The VTEC oil switch is normally closed, and grounds the reference voltage from the Engine Control Module (ECM) on the Blue/Black (BLU/BLK) wire. If the code sets at idle - 2500 RPM - and the Brown/Yellow wire has a good ground, then suspect a faulty VTEC oil pressure switch.
3. At approximately 2500-4000 RPM and when driving the vehicle, the VTEC system should turn on. To turn on the system, the ECM energizes the VTEC Solenoid valve and it allows oil pressure into the intake valve rocker arms, the oil pressure opens the VTEC oil pressure switch so the Engine Control Module (ECM) can verify that the VTEC did turn on correctly.
4. The code will set at idle to 2500 RPM if the reference voltage is not grounded. The code will set above 2500-4000 RPM if the VTEC oil switch does not open.
5. If the code sets at 2500-4000 RPM or higher, the problem can be a low oil level or pressure, or a malfunction in the VTEC assembly.
Potential Causes: Low Engine Oil
Plugged Oil Passage
Insufficient Oil Pressure
Plugged Oil Screen
Insufficient Oil Volume
Malfunctioning VTEC Oil Pressure Switch
Defective VTEC Solenoid

SOURCE: MY 2007 HONDA CRV CAR RADIO LOCKED AND IS ASKING FOR CODE

inside glove box there should be a sticker with the radio serial number and code. if that has been removed then you could try the honda owners site. you'll need the vin # and some other info
I was able to get the code recently for my 2010 CR-V

SOURCE: Engine light came on - yellow. Code: P0134 02

there is either a problem with the wiring going to the front oxygen sensor, or with the oxygen sensor itself. good luck!
