32 and 33 point towards a MAP sensor problem. They are affordable enough and easy enough to replace that it wouldn't hurt to replace it and clear the codes.

Gm obd1 codes 32 and 43


Code 32 is a problem with the EGR solenoid, and code 43 may be a problem with the knock sensor. Code 43 can set when the knock sensor is functioning correctly too.
You would need to get the troubleshooting charts for the codes to determine the problems.

My 95 eclipse is throwing codes 12, 31, 43, and 55 what do these codes mean?


12-cam shaft position Timing over retarded
31- HO2S heater Control Circuit Low (Needs a new O2 Sensor is what this is telling you)
43- HO2S Heater Control Circuit Low (Bank 1 Sensor 3)
55- HO2S Heater Resistance (Bank 1, Sensor 3)
All of those assume they are supposed to be preceded by a P00

If you are getting ODBI codes these are teh definitions you are looking for:
Code 12 Air flow sensor fault
Code 31 Knock sensor fault
Code 43 EGR fault
Code 55 AV valve position sensor

These may make more sense with that year model.

Found this for you on the web. Good luck.

What is code 43?

Code 43 is "fuel supply system."

This code will trip when the ECU and the readings from the o2 sensor don't get along(in layman's term or easy enough for Si Speed to understand biggrin.gif) read the above two threads).

How to diagnose and fix?

First things first, when was the last time you changed your O2 sensor? Start by replacing that first because most likely, that's the main culprit. Now, you may wonder why doesn't the CEL indicate code 41(heated o2 sensor)? Usually when the o2 sensor is completely dead, that code will trip. Also, even though the o2 sensor is working, the voltage or ground isn't 100% Because of that, it will correlate with code 43.

If replacing the o2 sensor did not help code 43 to disappear, next thing is to replace your fuel filter. A clogged fuel filter will also trip code 43.

Next up, did you install an aftermarket Fuel Pressure Regulator? I have a few friends with 3rd gen Preludes and both of them installed aftermarket FPR's and they too, trip code 43. Him and a lot of people who install aftermarket FPR's mess with the PSI and that will cause code 43 to appear(on a stock ECU mind you). Bring it back to stock PSI to help fight code 43.

Those are the 3 main culprits that will cause code 43 from my experiences. Injectors, spark plugs & wires, most likely anything "fuel' related that isn't working properly will also cause code 43.

hi there HO2S BANK 1 SENSOR 3 HEATER CIRCUIT LOW . this jiberish means that its an upstream preheated oxygen switch it may need to be replaced or one of the wires could be damaged take a look there is two o2 sensors on each side the more foreward ones are upstream and the ones located towards the muffler are called downstream . first thing id do is look for a bad or melted wire on one of the upstream sensors but in capital letters is the definition for code P0043 good hunting .
