I would first try and reset the Powertrain Control Module since you replaced the alternator. This will clear all the codes and turn off the check engine light. To do this, pull the No. 13 "clock backup" fuse from the passenger kick panel fuse box for 10 seconds then replace.

Now, you should also do the Honda "idle learn procedure". This lets the computer calculate what a no load idle condition is so it can adjust idle speed when the engine or alternator is put under various loads. To do this, make sure all electrical items are turned off. Start the engine and hold it at 3,000 rpm in park or neutral until the radiator fan comes on or until normal operating temp is reached (about 4 minutes). Now let the engine idle for a minimum of 5 minutes with no loads. If the radiator fan comes on during the 5 minutes, the amount of time it runs must be added to the 5 minute period--the goal being a period of at least 5 minutes without any loads on the engine or alternator.

Also check the vacuum line to the evap solenoid. It is on the top of the engine near the intake throttle body.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: 2000 honda accord code pulled was P1456 Evap

This may be as simple as your fuel cap not sealing correctly. You may want to throw on a new fuel cap and unhook the battery for 5 minutes to clear the code and try again. I have seen several types of cars throw these codes due to a bad fuel cap.
Hope this helps.

What is no dtc definition


There is a problem with the VTEC Oil Pressure Switch circuit or VTEC Solenoid Valve circuit

Make sure the oil level is good and it is not dirty. Dirty oil can clog the VTEC assembly so you might have to take it apart, clean it, and replace the seals.

I have an 02 accord that has the check engine light on. Its got 145000 miles on it. I got it scanned. The codes were p1259 vtec system circuit fault bank 1, p0420 catalyst system efficiency below...


Fix the P1259 code first. Are you using the recommended oil viscosity? If not, change that immediately. Also, check the screen in the Vtec solenoid for sludge buildup. If the variable valve timing isn't working properly, it can cause the P0420. If not fixed soon, that can destroy your cataltytic converter. The P1457 code is less important.

Code p1259


Hi there:
There is actually an old service news about this very code. there are two things that could be at fault but you will have to check a few things that are outlined in the article before knowing which parts need replacing... please read carefully below...

MIL with DTC P1259 - Vtec System Malfunction

On 1998 Accord L4s with VTEC, DTC P1259 (VTEC system malfunction) can set at idle or above 4,000 rpm:

If it sets at idle, the problem is with the VTEC pressure switch circuit (switch, connectors, or wiring).
If it sets above 4,000 rpm, the cause is low oil pressure in the VTEC system.

To find and correct the cause of the DTC, do this:
1. Use the PGM Tester to check the vehicle's freeze data or snapshot data to see when the DTC was set.
If it set at idle, go to step 2.
If it set above 4,000 rpm, go to step 4.

2. Disconnect the 2P VTEC pressure switch connector, and jump its two wires.

3. With the ignition switch ON (II), the PGM Tester should show that the VTEC pressure switch is ON.
If the Tester says the switch is ON, the wiring and connectors are OK, so the switch must be bad.
Replace the switch, clear the DTC, and return the vehicle to the customer.
If the switch is OFF, check for an open circuit between the switch and the ECM/PCM or between the switch and ground. After you repair the open circuit, recheck the switch, then clear the DTC, and return the vehicle to the customer.

4. Remove the valve cover, and check for a loose center head bolt on the intake manifold side. A loose bolt can cause a drop in pressure in the VTEC system.

If the bolt isn't loose, go to step 5.
If the bolt is loose, torque it to 22 lb-ft (29 Nm), turn it another 1/4 turn, and then turn it another 1/4 turn. If the bolt won't tighten, its threads are probably stripped.

5. Remove the VTEC rocker arms, and inspect them for sticking or missing synchronizer pistons or other valve train problems that could cause an oil leak.

If you find any piston or valve train problems, replace the faulty parts. Then clear the DTC, and return the vehicle to the customer.
If the pistons and the valve train are OK, do the DTC P1259 troubleshooting procedure on pages 6-7 thru 6-9 of the '98-99 Accord S/M.


Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Code P1259 what would cause this?


P1259 is the code for the VTEC pressure switch.

1. Check your oil level first, if oil level is low the code will come on. Add oil and reset the light.
2.you might have a bad Vtec oil pressure switch, try replacing it.

I took my 200 honda accord to auto zone to get a diagnostic done. the code was p1259. the ticket printout listed 4 things that would be probable cause. 1.open or short circuit condition 2.vtec solenoid...


CHECK VTEC SWITCH OIL PRESSURE.SHOULD BE 50 PSI @3000 RPM FOR THE S2000 OIL PRESSURE SHOULD BE 85 PSI @ 3000 RPM. IF OIL PRESSURE OKAY HAVE TO BE EITHER VTEC SWITCH FAULTY OR VTEC SOLENOID HAS FAILED.SOME TIMES PCM HAS FAILED TO THAT CONTROL CIRCUIT.

I have a 2005 honda civic si recently my check engine light came on showing the following codes they are P1259 and P1166


P1259 is a code for vtec malfunction usually cause by a bad vtec solenoid, vtec pressure sensor, low oil level, bad connection. Was oil change done? May want to check the oil level. P1166 is a code for a primary o2 sensor 1.
