recently pulled some trouble codes from my ECU, the KOEO code gives me 111, which the book says is a system pass, so I am assuming thats not a bad thing. I further went on to get the stored codes which are as follows (I get the same codes while doing a running test as well).
Leaking fuel injector bank 1 - EGR stuck open - Engine mechanical condition
1152: Oxygen sensor rich,
Some vehicles built prior to june 8, 2001 may exhibit a cold engine rough idle and / or a malfunction indicator lamp light with diagnostic trouble codes p0171, p0174, p1132, and p1152 in memory.
p0132 is heated oxygen sensor.......wiring short to positive and p1132 is heated oxygen sensor not switching, fuel trim, rich mixture.......intake/fuel system injectors MAF sensor, ECT sensor. hope this helps and if you need any more info just ask
The trouble code is related to a lean engine fuel trim problem. This particular code can be caused by a vacuum leak, low fuel pressure or faulty MAF or MAP. Check for vacuum leaks first, if you cant find any broken or cracked hoses, you might want to take it to a good shop and have live data read to determine if there is a component defective.
Check engine light will not go off untill you fix the problems, or if you erase the codes. Go buy a haynes or chiltons manual for your particular car or truck. Look in the emissions section of the book, and it will give you all code info.
If you want to reset your check engine light with a scan tool, you must hit erase after scan is complete.
Or, unhook your negative battery connection for about 10 minutes.
If your check engine comes back on, then you`ll need to fix the problems.
CODE P1132 LACK OF HO2S SWITCHING HO2S SIGNAL HIGH INPUT. CODE P1152 LACK OF HO2S 21 SWITCHING HO2S SIGNAL HIGH INPUT. LEAKING SIDEWALL ONE POSSIBLE CAUSE IS HIGH FUEL PRESSURE.AND LEAKING FUEL INJECTORS.YOU COULD HAVE FAULTY FUEL RAIL TEMPERATURE PRESSURE SENSOR.
Older cars used the OBD 1 system for retrieving codes, check your owners man, for the location of the diagnostic connector under the hood, use a compatible scanner, most newer scanner's have the cable needed for making the connection. Good luck!
Replace the brake/stop lamp switch at the brake pedal, also check for trouble codes. Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any codes which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.
