SOURCE: P1298 Code Fuel/Air Metering

Are you sure you wrote the correct code. According to Honda, P1298 is a high ELD circuit voltage. If what I just put is correct, Honda has a service bulletin as this is a common problem( it could be another fault, but this is the most likely choice).
The ELD has a bad solder joint. I have done several of these, you will need to replace the ELD, and this is how.

1 D/C the negative battery cable (make sure you know your radio code, it will be needed to use the radio again)
2 Unbolt the fuse box that is in the engine bay.
3 Attached to the fuse box underneath there is a plastic cover, remove this cover.
4 There is a 3 pin connector under this cover. Remove it
5 Flip the fuse box back over, there are 2 big fuses bolted down, a 40 A and a 80A
6 Under these fuses is the ELD, remove it and pull the bar that sticks out of it.
7 Stick the bar in the new ELD
8 Put everything back together. Do the idle learn (just idle the car for 10 minutes with no loads on such as radio, headlights etc..)


This is probably the first thing they will do if you bring it to Honda assuming the code you have is P1298.

I'm not sure why you got that code definition. P1259 in the factory manual reads, "VTEC system malfunction". According to the manual you are supposed to reset the powertrain control module (PCM) then road test--accelerating in first gear to over 4000 rpm and hold that rpm for at least two seconds. If the code does not repeat then do the road test two more times just to be sure. If the code does repeat during the three acceleration tests, then the VTEC pressure switch and solenoid valve should be checked. If the code does not repeat during the three acceleration tests, then the system had an intermittant fault. As for the TCS light being on, I know this may sound simple but is the TCS switch off? If it is, that will cause the light to come on. The TCS light is more applicable to an ABS brake system problem. If the transmission has a fault, you should see a diagnostic code that begins with P07xx or P17xx. The green D4 drive light may also blink. Based on your symptoms of excessive shock in 1-2 upshifts, the book suggests the shift solenoid valve C could be defective, or the 2nd clutch pressure switch or the circuit could be defective, or there could be foreign material in the separator plate orifice, or seven other possible causes. I would suggest clearing the code and replacing the transmission fluid with genuine Honda fluid and then see if the code and the symptoms return.

SOURCE: what does computer code p1131 manufacturing control fuel air metering mean

Code p1131 manufacturer control fuel air metering, on a 2003 Ford Taurus. Where is part? Is there an easy way to see if it can be fixed without buying the expensive part?

SOURCE: P1131 code Fuel Acturer control - Fuel air metering

In almost every Ford Product from 1990 to 1999 the most likely cause is the Mass Air Flow (MAF) Sensor.

Auto manufacturers have a cleaning cycle built into the MAF circuit. How it works is this; when the key is turned off a larger current is sent through this hot wire causing it to glow red hot, thus burning off any contaminants. Well, almost all auto manufacturers that is.
MAF sensors can get contaminated from a variety of sources: dirt, oil, silicon, spider webs, potting compound from the sensor itself, etc. When a MAF sensor gets contaminated, it skews the transfer function such that the sensor over-estimates air flow at idle (causes the fuel system to go rich) and under-estimates air flow at high air flows (causes fuel system to go lean). This means Long Term Fuel Trims will learn lean (negative) corrections at idle and learn rich (positive) corrections at higher air flows.
To confirm this disconnect the MAF sensor connector. This puts the vehicle into Failure Mode and Effects Management (FMEM). In FMEM mode, airflow is inferred by using rpm and throttle position instead of reading the MAF sensor. (In addition, the BARO value is reset to a base/unlearned value.) If the lean driveability symptoms go away, the MAF sensor is probably contaminated and should be replaced. If the lean driveability symptoms do not go away the MAF sensor is probably not contaminated.
When this happens Ford says you must replace the MAF since they cannot be repaired. With a dealer cost of about $177.00 and about 1.5 hours of labor the repair is not very expensive. However Ford is not correct. This problem can be fixed and it can be done by just about anyone.
What you need to do is go to the local Radio Shack and get a can of spray tuner cleaner, #64-4315. Or a MAF cleaner at any Auto Parts store. Disconnect the NEGATIVE battery cable and remove the MAF from the vehicle. Spray the inside of the MAF with the tuner cleaner. Be very careful when you spray the hot wire. It is very thin and if it breaks, you will have to replace the MAF. Clean it well and let it air dry for 15 or 20 minutes.
Don't use carburetor or brake cleaner. They leave a residue and you will be right back where you started. Use ONLY the tuner cleaner, MAF cleaner which dries residue free. When it's dry put it back in the vehicle and reconnect the NEGATIVE battery cable. You will need to drive the vehicle several miles to let the PCM "relearn" your specific driving conditions. Once that is done the codes will not come back and you should notice all the symptoms are gone as well.
Good luck and keep me posted, be glad to help you get your car running 100% soon.

SOURCE: Year 2001 XG300 P0115, P1159, P1191, P1193, P0115

P0115 - Engine Coolant Temp Sensr - open/short
P1159 - Variable Intake Motor Malfunction

P1191/P1193 Limp Home Valve - Low RPM

First, clean the throttle body and check for anything which might obstruct AIR FLOW to it.

The P1159 is the Variable Intake Motor Malfunction. this motor is either 'OPEN'... or 'CLOSED' position. It is located on/in the intake manifold (plenum) and is only opened when cruising... it is closed at idle. If it sticks 'OPEN' is can cause drivability issues.

Dont clean your throttle body yet..........Theres an idle air control valve{ black round top about the size of a 50cent piece} on the back of the throttle body, cleaners will ruin it. It mounts with 2 screws facing the back of the motor. This is what controls your idle.........

My check engine light came on. I went to autozone and received a dtc p1259 code. What does that mean


p1259 code is manufacturer control fuel air metering,--its a VTEC malfunction, Check the oil level in your car. Everytime I've seen this code it is because the oil level is low. VTEC works off of oil pressure and when the oil level is too low there is not enough oil pressure to push the VTEC in. My guess is you're about two quarts of oil low so it should cost you about $4.00 to fix the problem. If the oil level is correct then you'll need to take it to the dealer for diagnosis.

I had my check engine light come on & the code is a P1259 /fuel and air metering issue. Does anyone know what part this code is referring to that may need replaced? The car is running okay. However...


I suggest replacing the O2 sensor(s). These detect the level of carbon monoxide in the exhaust, and at a certain level the exhaust is then returned to the engine to be reburned, then sent back through the exhaust, catalytic converter, then the muffler.

Take the code type to an auto parts dealer, and verify what the code is specifically referring to.

If the engine was idling (running) rough, also repalce the air filter, fuel filter, spark plugs<-- find out gap setting; plug wires, distributor cap and rotor (if equipped).

Also, if you haven't recently had the fluids changed, have them changed as well, as the filters for each and the gaskets if needed.

NOTE: if you smell an unusual smell coming from your car; the smell of rotten eggs or such, then your catalytic converter may need replaced.

Please let me know if you need further assistance.

p1259 is a problem with the VTEC system. this system is for improved performance at higher rpm's. oil can get sludged up and clog the system, or the VTEC solenoid can just go bad. you can always have someone with a scan tool clear the codes to turn off the light, but until the problem is fixed, it will just keep coming back on

1992 Honda Accord LX. The D4 light blinks,car will not start.


(Curtorsey Automotive Helper)The light is blinking to make you aware of a tranny problem. You will have to pull the codes to determine exactly what the problem is. Being that you don't have a 96+, you will have to do this yourself or pay $70 at the dealership. It is simple, so I recommend doing it yourself.

It could be a cheap problem, it could be expensive, but you wont know until you pull the problem code.
Once you have the code, let us know what it is and we can further help. Also, I wouldn't drive it, as you don't know what the problem is, so it would be wiser to err on the side of caution.




To learn how to pull your own codes, go here and read everything:

If for some reason that isn’t sufficient for you, you may want to look at this:

Now you should have a code…and you probably want to know what the code means, so check out these pages. Between these 4 pages you will DEFINANTLY find your code and what part of the car it refers to.

Basically you need a new oxygen sensor, The fuel trim code is from the computer trying to adjust the fuel/Air mixture to compensate for the bad signal from the sensor. Just change the one closer to the engine, the one behind the Catalytic converter will thow a different code when it fails.
