98 Sportage error code help, please....

[Al Anganes]

Hi All,
My son has a 1998 Sportage, 4WD manual trans, 2L, 4 cylnder.

Engine has been idling rough, mileage has dropped pretty noticably. We did most of the standard "tune up" stuff - plugs, air filter, fuel filter, etc., as it was about time anyhow. Did not help much. Today got a "Check Engine" light. Borrowed a generic OBD scanner, it gave two codes:

P0107 & P0117

The scanner described the P0107 code as being "System too lean bank 1" and P0117 as "Coolant temp Circuit low input".

Looking up the codes on line Kia specific sites describes P0107 a bit differently as "MAP/BARO circuit low input".

What would "MAP/BARO circuit low input" point towards? Any ideas as to what i ought to check next? And what of the P0117 code? Thoughts, please?

Any help would be much appreciated.

Thanks very much!

The best first step is to just do a google search on "DTC P0117", etc, to get a general flavor for what a given code is all about. The P0117 code is likely suggesting a damaged ECT sensor. I'd start by replacing it, then reset the codes and see what happens then. (fyi the simple way to reset the codes is to just disconnect the battery for 5 or 10 minutes). If the P0107 reappears, then you could try cleaning the MAP sensor -- expose it (disconnect the air intake housing to do so), squirt some WD-40 in there and then blow in compressed air to evacuate any debris (NOTE: use only about 20 or 30lbs of pressure, since they are usually very delicate):

DTC Codes - P0100-P0199 – Fuel and Air Metering

P0100 Mass or Volume Air Flow Circuit Malfunction
P0101 Mass or Volume Air Flow Circuit Range/Performance Problem
P0102 Mass or Volume Air Flow Circuit Low Input
P0103 Mass or Volume Air Flow Circuit High Input
P0104 Mass or Volume Air Flow Circuit Intermittent
P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input
P0109 Manifold Absolute Pressure/Barometric Pressure Circuit Intermittent
P0109 Intake Air Temperature Circuit Malfunction
P0111 Intake Air Temperature Circuit Range/Performance Problem
P0112 Intake Air Temperature Circuit Low Input
P0113 Intake Air Temperature Circuit High Input
P0114 Intake Air Temperature Circuit Intermittent
P0115 Engine Coolant Temperature Circuit Malfunction
P0116 Engine Coolant Temperature Circuit Range/Performance Problem
P0117 Engine Coolant Temperature Circuit Low Input
P0118 Engine Coolant Temperature Circuit High Input
P0119 Engine Coolant Temperature Circuit Intermittent

Finally, with any vehicle with 100+k miles on it you should always be on the lookout for vacuum leaks, especially in any rubber elbows that connect to two ridged connections -- look for damage on the bottom of such elbows where the bend is at its maximum, where stress, vibration and friction tend to take their toll.

Thanks for the detailed reply. That give me a good list to start with.
Much appreciated.
