Use an electrical tester with a sharp point tip, and poke through the coating into the wire at every 5".

this is the best wat to test the wiring.

What does code 13 mean for a 2000 mercury cougar


If you mean P0113 then it is an intake air temperature circuit high output. Which means some of the possible problems could be a dirty air filter, defective intake air temp. sensor, defective MAF sensor, or faulty or corroded air intake temp sensor.
Now if it code
P0133 then the cause would be an O2 sensor. Which is bank 1 sensor 1.
In some cases on older vehicles code 13 means there are no problems but that was back in 95 and before.

I have a 95 geo prizm 1.6 l engine I found out that my downstream oxygen sensor before I bought it some one had cut the wires and spliced them with what I think is a vacuum cleaner cord and the wires r...


If you understand what is going on under your hood.. the wires being spliced May not be your problem. Check that they are not bare if they are then fix it. The problem may be a dirty intake due to the engine overloading all the time. When it's cold it runs good since that's what the choke does. Take your air filter off and follow the tubing to the aluminum intake. Clean that out very good with a rag full of carburetor cleaner.

1995 GEO-PRIZM 1.8L eng.Surges under all driving conditions


If you have a check engine light on you can pull the code and it should tell you if its an o2 sensor or not. I usually replace them when i do a major tune up. Change your spark plugs, wires, cap and rotor (if your car has cap and rotor), oil and filter, tranmission oil and filter, air filter, fuel filter, coolant flush, and o2 sensors. Thats a major tune up. Also spray a little brake cleaner above the engine around the intake and vacuum line and see if the engine reacts to it. If does you have a vacuum leak which may cause you to surge aswell. You may also want to change your iac motor and throttle postion sensor aswell seeing as they have alot to do with idle and acceleration. Without an engine code its hard to tell but those are my basics gor that problem. You can ask a mechanic for a diagnostic then you can fix it yourself if thats what you are trying to do. Hope this helped good luck

Does a 1993 geo prizm 1.8L lsi have two temp sensors?


buy the manual. and RTM,
and yes, Air , water, and on a stock car up to 3 coolant sensors.
The ECT runs the ECU. tells ECU coolant temp.
my guess is the coolant gage is dead? RTM
on most 93 car, the Guage has its own sensor, (isolated)

89-02
joint venture, GM/toyota with 3 engine used.
1.8L or 1.6L
toy engine, 4aFE, 7AFE or 4AG
open hood look
or use the GM RPO tag
or Use the VIN to find motor used.

Have an engine light problem. done a dionostic check code is 24 wich indicates that the problem is with the IAT (intake air temp) sensor but with inquiring with my local toyota repairer. The V6 dosn&#


Of course the V6 has this sensor. It is vital to get the right fuel-air mixture.
Depending on your location, it may be mounted in the rear side of the air cleaner housing or in the mass air flow meter as here, p451, with test procedures

Check engine light came on after throttle intake cleaner was used


it possibly clogged the o2 sensors when it cleaned the gunk out and the maf might even be on the air box or bolt on the intake directly or it can be in the tube but probbably need to check and see what the codes are with a scanner
