@KIAMOTORS The Power to Surprise® GROUP MODEL Engine Sorento (BL) 2003-2006MY DATE January 2013 NUMBER PS233 SUBJECT : UNUSUAL FUEL TRIM VALUES AND/OR MIS FIRE CODES AFTER INCORR ECT ENGINE REPAIR If after an engine repair you encounter a complaint relating to MIL on (OTC P030X) with a misfire during acceleration and/or you find unusual fuel trim values outside the normal parameters, check for proper installation of the fuel injector wire harness. It is possible that the electrical connectors for Bank 1 and Bank 2 have been installed backwards (left bank versus right bank). If the fuel injector wiring harness is installed incorrectly, the H02S voltages will not fluctuate normally. Bank 1 H02S will output approximately 0 volts while Bank 2 H02S output will remain around 1 volt, as the ECM is trying to compensate with fuel trim adjustments. Long term fuel trim values will correspond to the voltage output of the H02S. • Low H02S output voltage = Increased enrichment; • High H02S output voltage= Decreased fuel enrichment towards lean. Injector connector B-06 (fuel injector #5 , right bank) is closest to X-45: Use it for identification purposes. Route the harness connectors to the proper location and retest. Refer to the sample screenshots on page 2 to verify the condition. Note that these screenshots are from Hi Scan Pro (G OS screens will show similar information). lniector Connoclor #6, B--07 Page 1 of 2 Current Data (INCORRECT) l Current Data (CORRECT) 2-.(.1 ~ll[ lfl MT - ( IL ril iN .~/1 e1 "'' 111n T•1n111 i ';)) VT fV[L r11m 0 1 1 0 .. t.:. .~I •r• tt l l / t f111 L tMtr"82' 1111 tl'GIM r,,.u;p f I le Output Voltage From H02s (INCORRECT) ' ~ I' p:-;-;-- ' •.u.J I tllJ - 1A 9. f >"I j 7.;:;;i UU..1 II "'• fl ""' r11, I Tlln..
