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: code PO131

Code PO131 is O2 sensor circuit low voltage , bank 1, sensor 1. That sensor I would say is the one in the exhaust manifold. I would check voltage to the sensor from the computer. If the voltage is not 5 volts, then it could be a computer problem or a wiring problem. I have seen factory wiring and connectors give a voltage problem. Check for a damaged or burnt, pinched wire. You need to know for sure that the voltage is correct to the sensor. Intermittent problems are hard to trace , but patience and knowledge helps.

I changed head and cam om a 1989 honda civic lx.now it runs rough. whats the problem?


check for missing vacuum hoses. run fault codes to check for wires not properly connected . Have a compression test done as broken timing belts generally bend valves . IT may not be noticeable but will be enough to affect the engine performance.

Brake lights on 1989 honda civic went out...what is the problem? brake switch maybe? All fuses are fine


Check the brake light switch above the brake pedal with a volt meter, when the pedal is pushed you should have 12 volts in and out.

89 honda civic fails smog


bingles,,,have you changed the oilseals on the valve stems or used the old ones?these tend to harden after a few years and even a slight leak may lead to high emissions, also v,important did you use the old head gasket or replace it? always use a new gasket as an old one has already been compressed and may cause a cross-flow leak into one or all of the piston chambers.
hope this helps.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

Check engine light


P0041 Downstream Oxygen Sensors Swapped From Bank To Bank
How does a P0041 code trigger the check engine light? This code will trigger the light to come on under the following condition:

The Heated Oxygen Sensor Monitor, a strategy built into the computer, determines if the Heated Oxygen Sensor (HO2S) signal response for a change in fuel trim corresponds to the correct engine bank. If a response from the Oxygen Sensor being tested is not indicated, a trouble code will be set and the MIL (Malfunction Indicator Lamp) will illuminate.
Possible Causes:
Crossed Heated Oxygen Sensor harness connectors
Wiring swapped from one Oxygen Sensor connector to the other
Wiring changed at the computer connection or in the related harness

Need to pull and reed trouble codes for a 1989 honda


there is a jumper wire on the passenger side kick panel, short this wire with a paper clip and turn your ignition to run, the CEL check engine light will flash the number of the trouble code,
long flashes = 10's
short flashes = 1's
so a code read like this
L<L<L<S<S<S<S<S
would be 35
there will be short pauses between flashes and a long pause between separate codes,
hope this helps

1999 Honda Civic EX fault codes 1366 and 1399


This code is not documented so the code reader is giving a false reading.
If the car runs OK and check engine light is not on, I would forget about it.
