Ok well my was on so i hooked up the computer to it and it came up wit these 172-EGO NOT SWITCHING 176-EGO NOT SWITCHING 556-Fuel pump relay primary CKT 628-Excessive converter Clutch slippage :help2: How do i fix all this or wut ? how do i figure out the problem i just want my engine light off so then i can try to turn off my ABS one off also lol plz help guys :drunk:
Found this for your fuel code and o2 sensor codes Diagnostic Trouble Code (DTC) 543/524 indicates a fuel pump secondary circuit failure between the B(+) supply and the FPM connection to the power-to-pump circuit. Possible causes: No Starts: -- Open circuit between the B(+) supply and the FPM connection to the power-to-pump circuit. -- Fuel pump relay contacts always open. Engine Starts: -- Left/Front HO2S short to power -- Damaged Powertrain Control Module (PCM). ** Does engine start? NO = fix open in circuit or replace CCRM. RERUN test. YES = continue CHECK FRONT/LEFT HO2S FOR SHORT TO POWER NOTE: Due to the internal circuitry of the PCM, a Left/Front HO2S signal short to power could produce a DTC 542/543. * Key off. * Disconnect left or front HO2S. * Measure resistance between HO2S signal pin and KEY POWER pin at the HO2S connector. ** Is resistance greater than 10,000 ohms? NO = replace the O2 sensor. RERUN test. YES = continue CHECK HO2S CIRCUIT FOR SHORT TO POWER * Key off. * Left or Front HO2S disconnected. * Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary. Leave PCM disconnected. * Key on. * Measure voltage between the HO2S signal at the HO2S vehicle harness connector and chassis ground. ** Is voltage less than 1.0 volt? YES = replace ECM, reconnect the O2. RERUN test. NO = fix short circuit, reconnect the ECM and O2. RERUN test. END ******************************** Continous memory 543 ** Also a continous memory code 556/557? YES = skip ahead to section after next YES/NO quesions NO = continue A Continuous Memory DTC 524/543, without the presence of a Continuous Memory DTC 556/557, indicates that during vehicle operation, one of the following has occurred : -- Open in the B(+) circuit between B(+) and the fuel pump relay. -- Fuel pump relay contacts opened. -- Open in the power-to-pump circuit from the CCRM/LFP relay to the FPM splice. -- Left/Front HO2S circuit short to power. * Start engine. * Check for engine stall/stumble while performing the following (also, if possible, listen for fuel pump turning off): -- Shake, wiggle, bend the fuel pump relay B(+) circuit to the CCRM/LFP relay. -- Lightly tap the CCRM/LFP relay (to simulate road shock). -- Shake, wiggle, bend the power-to-pump circuit from the CCRM/LFP relay to the FPM splice. * Key off. * Inspect the CCRM/LFP relay connector and B(+) connector terminal for corrosion, damaged pins, etc. ** Is fault indicated/found? YES = ISOLATE fault and SERVICE as necessary. CLEAR Continuous Memory DTC. RERUN test. NO = Under certain conditions, a Continuous Memory DTC 524/543 may have been set without a Continuous Memory DTC 556/557, even though a fault has occurred in the fuel pump primary circuit. continue A Continuous Memory DTC 556/557 indicates a fuel pump primary circuit failure has occurred during vehicle operation. Possible causes are: -- Open VPWR in the CCRM. -- Open coil in fuel pump relay. -- Open in fuel pump circuit (PCM Pin 22). * Start engine. * Check for engine stall/stumble while performing the following (also, if possible, listen for fuel pump turning off): -- Shake, wiggle, bend the EEC-IV vehicle harness fuel pump circuit (Pin 22) between the PCM and the CCRM. -- Lightly tap the CCRM to simulate road shock. * Key off. * Inspect the PCM connector and the fuel pump relay connectors for corrosion, damaged pins, etc. ** Is fault indicated/found? YES = ISOLATE fault and SERVICE as necessary. CLEAR Continuous Memory DTC. RERUN test. NO = continue CHECK LEFT/FRONT HO2S CIRCUIT FOR SHORT TO POWER NOTE: Due to the internal circuitry of the PCM, an intermittent left/front HO2S signal short to power could produce a Continuous Memory DTC 542 or 524/543. * Key off. * Install breakout box, if applicable. * Breakout box installed, PCM disconnected. * Connect a test lamp between the left/front HO2S test (pin 43) and test pin 40 at the breakout box. * Key on, engine off. * Observe test lamp for an indication of a fault while performing the following (the light will turn on bright when a fault is detected): -- Shake, wiggle, bend the left/front HO2S circuit from the HO2S sensor to the PCM. -- Lightly tap the HO2S sensor (to simulate road shock). ** Is fault indicated? YES = ISOLATE fault and SERVICE as necessary. CLEAR Continuous Memory DTC. RERUN test. NO = take to dealer for complicated analysis (sorry) HOPE THIS HELPS :thumb: imp2: :thumb:
