86 GL 4dr

i'm getting code 22 and code 24 how do i get rid of these codes???

[Calebz]

Is the car carb'd or does it have SPFI?.. Or is it possibly MPFI turbo(like mine )

87 is supposedly the first 'official ' year for the SPFI cars, but I have seen that subaru sneaked a few in in 86 as well

Whichever it is, to get rid of the codes, you must fix whatever is causing them.

Here is some readin for you

There are self diagnostic connectors on all models which, when
connected together with the key in the ON position (engine off) flash
diagnostic codes through the LED light on the Oxygen Monitor on the
ECU. The connectors are under the steering wheel, to the left of the
Oxygen Monitor on most models. On Carbureted and Single-Point Fuel
Injected Models, the test connectors are located on the engine side
of the firewall, on the driver's side.

There are four test modes. With NEITHER test connector connected, and the key in the ON (engine off) position, the light will display codes
that relate to starting and driving. With ONLY the "Read Memory"
connector connected, historic codes will be displayed. With ONLY the
"Test Mode" connector connected, a dealership technician can perform
dynamic tests. The last mode is for clearing codes (see below).

The codes are displayed as pulses of the LED mounted on the module.
The long pulses (1.2 Seconds) indicate tens and the short pulses (.2
seconds) indicate ones. Pulses are separated by .3-Second pauses, and
multiple codes are separated by 1.8-Second pauses. (See Example Below)


The codes can be viewed on
either the Oxygen Sensor Monitor or the Malfunction Indicator Lamp
(Check Engine Light) on the dash, depending on the year and type of fuel system your car has



--- CLEARING CODES ---

Codes will clear only when the faulty system or circuit is repaired.
After making the repairs, codes can be cleared by connecting TWO pairs
of connectors, the "Self-Diagnostic" connectors, and the "Read Memory"
connectors that are usually located right next to the diagnostic
connectors. To begin, start with a warmed up engine, turn the engine
off, connect both pairs of connectors, then start the engine. This
should clear the codes. If this fails to clear the codes, consult an
Authorized Subaru Technician
