Checking components, intake system
Check using information about combined diagnostic trouble codes if this trouble code is a root problem or not. If the diagnostic trouble code is stored as lone diagnostic trouble code or if it is indicated as a root problem, continue with the troubleshooting below, otherwise follow troubleshooting for the diagnostic trouble code pointed out as root problem.
ECM-130A can be generated due to a damaged mass air flow sensor. An indication of this is that the engine control system has increased the fuel amount at partial load and then primarily the value for "Lambda adaption, upper partial load". If any of the diagnostic trouble codes ECM-260A, ECM-261A, ECM-270A and/or ECM-271A with trouble type Upper limit is stored together with ECM-130A, troubleshoot according to any of these diagnostic trouble codes, otherwise continue according to the following.
Read off "Air mass, correction value" and check in which way the air adaption has gone. A low value, less than approx. 0.85 indicates a clogged crankcase ventilation and/or dirty throttle module. A higher value, greater than approximately 1.15, indicates a (smaller) air leak somewhere in the intake system.
High value
Check the induction system for air leaks.
Check that the intake air temperature (IAT) sensor and boost pressure sensor are correctly installed. Check for air leakage around the components.
Note. Even extremely small air leaks can cause this diagnostic trouble code (DTC) to be stored.
Low value
For markets where upgraded software, released during year 2006 or later, is available, then if ECM-91A7 and/or ECM-91B7 is stored together with ECM-130A, then the throttle module shall be cleaned.
Otherwise, the solution to the diagnostic trouble code/symptom is to load the upgraded software in the vehicle.
For markets where upgraded software, released during year 2006 or later, is not available, the solution is to clean the throttle module and the crankcase ventilation.

| CAUTION | In order for Electronic throttle module (ETM) to reset any reconfigurations as well as delete internally stored problems, the following must be performed: Turn off the ignition and then wait three minutes for the main relay or system relay to release the voltage feed to, among others, Electronic throttle module (ETM). Wait another three minutes, but if the electric cooling fan is running you have to wait another two minutes after the cooling fan has stopped, to ensure that Electronic throttle module (ETM) is shut off correctly. If this is not done correctly, diagnostic trouble codes may remain even after deleting diagnostic trouble codes and any reconfiguration may remain, despite the problem being fixed. |

HINT: This diagnostic trouble code can be caused by a damaged mass air flow sensor.
Check that lambda adaptations are within the specified normal values.
Incorrect lambda adaptations can indicate a faulty mass air flow (MAF) sensor.
HINT: Use the adaptations for the mass air flow (MAF) sensor and leak flow (parameter read out) to determine how much the system has adapted.
An adaptation on one or both parameters that is less than approximately 0.85 indicates blocked crankcase ventilation and/or a dirty electronic throttle module (ETM).
Adaptations greater than approximately 1.15 indicate a (smaller) air leak somewhere in the intake system.

Checking the engine coolant temperature (ECT)
- Fault-tracing must begin with the engine cold (+20 °C) so that the engine coolant temperature (ECT) sensor can be tested over as wide a temperature range as possible
- Switch off the climate control system
- Start the engine. Read off the engine coolant temperature (ECT). Check that the engine coolant temperature (ECT) is within its permitted range and corresponds with the engine warming up.
Is the temperature reasonable?
- YES Refer to «Checking the thermostat»(ref-440262-S25173626422011121400000)
- NO Refer to «Replacing the component»(ref-440262-S00602267472011121400000)
Checking the thermostat
- Start the engine. Run the engine until the engine coolant temperature (ECT) reaches approximately 100 °C
- Activate the engine cooling fan (FC) with the engine running
- Wait approximately 90 seconds and then shut-off the engine cooling fan (FC). Read off the engine coolant temperature (ECT). If the temperature is 85 °C or lower when the fan stops, the thermostat is defective.

Replacing the thermostat
Note. This diagnostic trouble code (DTC) is stored if the engine coolant temperature (ECT) sensor freezes. This may happen if the coolant level is low or there is too little glycol in the coolant. Check the engine coolant level and its freezing point. Remedy as necessary.
The engine control module (ECM) has registered that the actual temperature increase has deviated from the calculated temperature increase. This deviation is due to a defective thermostat.
Try replacing the thermostat. See Temperature sensor engine coolant, replacing .
