I have the car listed above and have been have problems with it storing codes. The first code that I had was 172 so I replaced both oxygen sensors. Ihave also replaced, fuel charge sensor, injectors, plugs and wires, thermostat. The car now thows a code of 1132, If you could direct me in the correct direction that would be helpful.

52) Check Fuel Pressure
Release fuel system pressure. With ignition off, install fuel pressure gauge. Using scan tool, access OUTPUT TEST MODE. Command fuel pump on. Note fuel pressure. For fuel pressure specifications, see FUEL PRESSURE SPECIFICATIONS article. If fuel system pressure is not as specified, go to CIRCUIT TEST HC . If fuel system pressure is as specified, go to step 55).

53) Check System Ability To Hold Fuel Pressure
With fuel pressure gauge installed, cycle ignition from OFF to ON position 3 -4 times to pressurize fuel system (DO NOT start engine). If fuel pressure does not remain within 5 psi (34 kPa) of maximum pressure after one minute, go to CIRCUIT TEST HC , step 5). If fuel pressure remains within 5 psi (34 kPa) of maximum pressure reading for one minute, proceed as follows:

"� For no- start vehicles, go to step 55).
"� For DTCs P1130, P01150, P0171, P0172, P0174 and P0175, go to next step.

Disconnect Inertia Fuel Shutoff (IFS) switch. Crank engine for 5 seconds. If fuel pressure remains within 5 psi (34 kPa) of maximum pressure, reconnect IFS switch and go to next step. If fuel pressure drops
more than 5 psi (34 kPa), electronic engine control system is not cause of no- start.
Reconnect all components. See TESTS W/O CODES - EEC-V article for further diagnosis of no- start.

56) Check Fuel Injector & Circuit Resistance
Turn ignition off. Disconnect PCM 104 -pin connector. Inspect connector for loose, damaged or corroded terminals. Repair as necessary. Install Breakout Box (014 - 00950), leaving PCM disconnected. Measure and record resistance between suspect fuel injector circuit test pin and test pin No. 71 at breakout box. Refer to FUEL INJECTOR INJ CIRCUIT IDENTIFICATION table. Resistance should be 11 - 18 ohms. If resistance is not as specified, go to next step. If resistance is as specified, go to step 59).
NOTE: If misfire DTCs are present with fuel control DTCs, use misfire DTCs to determine which fuel injector circuits require testing.

57) Check Resistance Of Fuel Injector Circuit
Turn ignition off. Disconnect suspect fuel injector connector. Measure resistance between test pin No. 71 at breakout box and VPWR terminal at suspect fuel injector wiring harness connector. Also, measure resistance between fuel injector signal test pin(s) at breakout box and same fuel injector circuit terminal at suspect fuel injector wiring harness connector. If all resistance readings are less than 5 ohms, go to next step. If any resistance reading is 5 ohms or more, repair open circuit.

58) Check Fuel Injector Circuit For Short To Power Or Ground

If test light glows dimly, system is functioning properly. Reconnect all components and go to next step. If test light does not glow dimly (no light/bright light), replace PCM.

60) Check Fuel Injector Flow & Leakage
Turn ignition off. Remove breakout box. Reconnect PCM and fuel injector connector(s). Use Rotunda fuel injector tester from Fuel Tester Kit (113 -00114) to flow test fuel injectors. Follow injector tester instructions. If fuel injector flow or leakage rate is not okay, replace defective fuel injector(s). If flow rate for each fuel injector is okay, proceed as follows:

"� For DTCs P1131 and P1151, go to next step.
"� For DTCs P0171, P0174, P1130, and P1150, go to step 62).

Connect a jumper wire between HO2S SIG terminal at suspect HO2S wiring harness connector and negative battery terminal. Perform KOER ON-DEMAND SELF- TEST . If DTC P1131 or P1151 is present, remove jumper wire and go to next step. If DTC P1131 or P1151 is not present, check PCM connector and repair as necessary. If connector

Start engine and operate at 2000 RPM. If DVOM reads less than .4 volt within 30 seconds, go to step 70). If DVOM does not read .4 volt within 30 seconds, replace
HO2S.

NOTE: A break in step numbering sequence occurs at this point. Procedure skips from step 66) to step 70). No test procedures have been omitted.

70) Monitor HO2S PID
Start engine and allow to idle. Ensure engine is at normal operating temperature. Using scan tool, select HO2S PID from PID/DATA monitor menu. Observe PID value while wiggling and bending wiring harness between HO2S and PCM. If PID voltage stays high (more than .45 volt) or stays low (less than .45 volt), isolate fault and repair as necessary. If PID voltage switches, go to next step.

71) Monitor HO2S PID During Test Drive
Using an assistant, test drive vehicle under various conditions while observing HO2S PID. If PID voltage switches from about .4 to .6 volt, system is okay and testing is complete. If voltage does not switch from about .4 to .6 volt, replace HO2S.

"� HO2S 12, test pin No. 35.
"� HO2S 22, test pin No. 61.

Also, measure resistance between test pin No. 91 (SIG RTN) at breakout box and SIG RTN terminal at suspect HO2S wiring harness connector. If any resistance reading is 5 ohms or more, repair open circuit. If all resistance readings are less than 5 ohms, go to next step.

85) Check HO2S Circuit
Turn ignition off. Connect scan tool to DLC. Reconnect suspect HO2S and PCM connectors. Turn ignition on. Using scan tool, select appropriate HO2S PID from PID/DATA monitor menu.

If PID voltage is more than 1.5 volts, go to step 88). If PID voltage is 1.5 volts or less, go to next step.

86) Check Ground Circuit In PCM
Turn ignition off. Disconnect PCM wiring harness from breakout box. Measure resistance between test pins No. 103 (PWR GND) and No. 91 (SIG RTN) at breakout box. If resistance is less than 5 ohms, remove breakout box. Reconnect PCM wiring harness to PCM and go to next step. If resistance is 5 ohms or more, replace PCM.

87) Check HO2S PID
Connect a jumper wire between VPWR and HO2S SIG terminals at suspect HO2S wiring harness connector. Turn ignition on. Using scan tool, select appropriate HO2S PID from PID/DATA monitor menu. If PID voltage is more than 1.5 volts, replace HO2S. Perform HO2S MONITOR REPAIR VERIFICATION DRIVE CYCLE.

NOTE: A break in step numbering sequence occurs at this point. Procedure skips from step 88) to step 100). No test procedures have been omitted.

100) KOER DTC P0127
DTC P0127 indicates that HO2S heater was not on during KOER self -test and testing of HO2S did not occur. Possible cause is cool exhaust system. Connect scan tool to DLC. Using scan tool, access all HO2S heater PIDs. If all PIDs indicate ON, repeat QUICK TEST . If any PIDs indicate OFF, operate engine until all PIDs are on. Repeat QUICK

NOTE: A break in step numbering sequence occurs at this point. Procedure skips from step 100) to step 110). No test procedures have been omitted.

110) KOER P1128 & P1129
These DTCs indicate that during KOER self -test, one or both HO2S signals were crossed from bank to bank. DTC P1128 refers to HO2S in front of converter. DTC P1129 refers to HO2S behind converter. Possible causes for these faults are:

"� Crossed HO2S connectors.
"� Crossed HO2S wiring at HO2S connector.
