Ems fault codes 224

Fault code p0336 this code occurs when engine rpm goes too high which could happen under some mechanical related circumstances and is not necessarily related to a problem with the engine management system 224

Fault code p0654 if this code occurs and tachometer works normally disregard this fault code 224

General 224

Section 05 engine management power tek subsection 02 diagnostic procedures 224

Supplemental information 224

The faults registered in the ecm engine control module are kept when the battery is disconnected important after a problem has been solved ensure to clear the fault s in the ecm using the vck this will properly reset their states many fault codes at the same time is likely to be burnt fuse s for more information pertaining to the code faults status and report refer to b u d s online help or to the ems fault code table 224

When using the service action suggested in the fault section of b u d s the system circuits are referred to as da 41 which means connector on the ecm and the circuit 41 224

Fault code p1102 tps out of range fault it is caused by the sensor reading going out of its allowable range this fault can occur during the whole range of movement of the throttle to diagnose this fully it is recommended to operate the throttle through its full range it is also recom mended to release the throttle quickly as this may also reveal a fault that is intermittent 225

Fault code p1104 tps adaptation failure fault it is caused by the idle position moving out of an acceptable range following problems can be caused by a tps adaption failure idle speed is out of range engine stops when throttle is released quickly engine runs inconsistent in low partload or low rpm 225

Ems fault codes 649

Faults which are reported in b u d s fall into two groups tps faults and adaption faults these are dis played on the b u d s system as tps out of range and tps adaptation failure 649

General 649

Many other codes use the engine pilot lamp and the beeper to indicate a problem refer to b u d s for possible causes and service actions 649

Monitoring beeper coded signals 649

Section 04 engine management sdi subsection 02 diagnostic procedure 649

The faults registered in the ecm engine control module are kept when the battery is disconnected important after a problem has been solved ensure to clear the fault s in the ecm using the vck this will properly reset the appropriate counter s this will also record that the problem has been fixed in the ecm memory many fault codes at the same time is likely to be burnt fuse s for more information pertaining to the code faults state count first etc and report refer to b u d s online help 649

The following chart is provided to help in diagnosing the probable source of simple troubles 649

Tps throttle position sensor faults 649

Troubleshooting 649

Manual start models fault code p0616 this code will always be present disregard this code as it is not applicable since the starter relay wiring is factory installed the ecm detects an open circuit because the starting relay is not installed 650

Section 04 engine management sdi 650

Subsection 02 diagnostic procedure 650

Supplemental information 650

Tps adaptation failure fault it is caused by the idle position moving out of an acceptable range following problems can be caused by a tps adaption failure idle speed is out of range engine stops when throttle is released quickly engine runs inconsistent in low partload or low rpm 650

Tps out of range fault it is caused by the sensor reading going out of its allowable range this fault can occur during the whole range of movement of the throttle to diagnose this fully it is recommended to operate the throttle through its full range it is also recom mended to release the throttle quickly as this may also reveal a fault that is intermittent 650

When using the service action suggested in the fault section of b u d s the system circuits are referred to as da 41 which means connector a on the ecm and the circuit 41 650

Warning 657

Caution ensure all terminals are properly crimped on wires and connector housings are properly fastened before replacing an ecm always check electrical connections make sure that they are very tight and they make good contact and that they are corrosion free check if wiring harness shows any signs of scoring particularly check ecm ground connections ensure that contacts are good and clean a defective module could possibly be repaired simply by unplugging and replugging the ecm the voltage and current might be too weak to go through dirty wire terminals check careful ly if terminals show signs of moisture corrosion or if they look dull clean terminals properly and then coat them prior to assembling as follows if the newly replaced ecm works try the old one and recheck if it works ensure that all electronic components are genuine any modification on the wiring harness may lead to generate fault codes or bad operation note for diagnostics purposes use vehicle communication kit vck see dia 658

Resistance measurement 658

Section 04 engine management sdi 658

Subsection 03 component inspection replacement and adjustment 658

The resistance value for usual resistor or windings such as injectors increases as the temperature increases however some of our temperature sensors are ntc types negative temperature co efficient and work the opposite which means that the resistance value decreases as the tempera ture increases take it into account when mea suring at temperatures different from 20 c 68 f use this table for resistance variation relative to temperature for temperature sensors 658

To perform verifications a good quality multimeter such as fluke 111 p n 529 035 868 should be used pay particular attention to ensure that terminals are not out of their connectors or out of shape the troubleshooting procedures cover problems not resulting from one of these causes 658

When measuring the resistance with an ohmme ter all values are given for a temperature of 20 c 68 f the resistance value of a resistance varies with the temperature do not touch the sensor itself it may cause wrong result during measure ment because of body heat 658

Connector identifications 659

Disconnect the desired connector from ecm and reconnect on the tool connector probe required terminals directly in the tool holes 659

Ecm connectors 659

Section 04 engine management sdi subsection 03 component inspection replacement and adjustment 659

The most recommended and safest method to probe ecm connector terminals is to use the ecm adapter p n 420 277 010 this tool will prevent deforming or enlarging terminals which would lead to bad ecm terminal contact creating intermittent or permanent problems 659

The resistance value of a temperature sensor may test good at a certain temperature but it might be defective at other temperatures if in doubt try a new sensor also remember this validates the operation of the sensor at room temperature it does not validate the over temperature functionality to test it the sensor could be removed from the engine air si lencer and heated with a heat gun while it is still connected to the harness to see if the ecm will detect the high temperature condition and gener ate a fault code 659

Fuel injector replacement 663

If it does not read 12 v check the corresponding fuse s relay and continuity of circuit if continuity is faulty repair wiring harness 663

If resistance value is correct check wiring of cor responding relay if good try a new ecm refer to ecm replacement procedures elsewhere in this section if resistance value is incorrect repair the wiring harness connectors or replace the wiring harness between ecm connector and fuel injector 663

If resistance value is incorrect replace the injector reconnect the injector and disconnect the con nector a from the ecm as well as the engine vehicle connector using a multimeter check resistance value be tween terminals as shown in the table below 663

Faults which are reported in b u d s fall into two groups tps faults and adaption faults these are dis played on the b u d s system as tps out of range and tps adaption failure 1133

It is caused by the idle position moving out of an acceptable range following failures can be effected by a tps adaption failure idle speed is out of range engine stops when throttle is released quickly engine runs inconsistent in low partload or low rpm 1133

It is caused by the sensor reading going out of its allowable range this fault can occur during the whole range of movement of the throttle to diagnose this fully it is recommended to operate the throttle through its full range it is also recom mended to release the throttle quickly as this may also reveal a fault that is intermittent 1133

The resistance value of a temperature sensor may test good at a certain temperature but it might be defective at other temperatures if in doubt try a new sensor also remember this validates the operation of the sensor at room temperature it does not validate the over temperature functionality to test it the sensor could be removed from the engine air si lencer and heated with a heat gun while it is still connected to the harness to see if the ecm will detect the high temperature condition and gener ate a fault code 1137

Caution do not disconnect the ecm connec tor needlessly they are not designed to be dis connected reconnected repeatedly 1138

Caution probe on top of terminal only do not try to probe inside terminal or to use a pa per clip to probe inside terminal it will dam age the square shaped terminal and this could lead to improper function of the engine man agement system 1138
