VERIFICATION

HINT: After carrying out the repair, check that the fault has been remedied.

Scheme 53

Scheme 54

1. Test drive the car and ensure that there is a fuel shut-off. The easiest way to do this is to drive at approximately 80 km/h and abruptly release the accelerator pedal (AP) for at least 5 seconds
2. Connect VCT2000 or appropriate scan tool to the data link connector (DLC) without switching off the engine. NOTE: If the engine is switched off, the stored fault status will be erased and the test drive will have to be repeated. Read off the diagnostic status and the fault status for the diagnostic trouble code (DTC). Check that the diagnostic is "Completed" and that the fault status is "No fault detected". The function is faulty if the fault status is "Fault found".

Is the fault status "No fault detected"?

1. YES VERIFIED: Troubleshooting has been completed.
2. NO Refer to «INFORMATION»(ref-466654-S29429393242012042500000)

CHECKING FUSES

All heated oxygen sensors are supplied with voltage with the same lead. If the lead is damaged, e. g., fuse on the lead, then diagnostic code for heating for all heated oxygen sensors will be stored.

Therefore, check first if diagnostic trouble codes for heating are also stored for other heated oxygen sensors.

HINT: Brake vacuum pump is supplied with voltage via the same lead as the heated oxygen sensors. A damaged brake vacuum contact can lead to the pump running continuously and in the long-term be overheated and damaged. In turn, this leads to damaged fuse.

HINT: Therefore, check the brake vacuum switch and pump before any continued troubleshooting is done on the heated oxygen sensors.

INFORMATION

This diagnostic trouble code is a collective code for diagnoses regarding electrical malfunctions on the heated oxygen sensor and its heating.

The diagnostic trouble code never appears alone. Therefore, troubleshooting takes place from another diagnostic trouble code for electric fault on rear heated oxygen sensor.

For further information on this diagnostic trouble code, see Diagnostic trouble code (DTC) information.

1. Ignition on. Activate the injector that relates to the diagnostic trouble code (DTC) to check whether the fault is permanent or intermittent. The fault is intermittent if the injector clicks when activated. The fault is permanent if the injector does not click when activated.

1. Continue Refer to «CHECKING THE COMPONENT AND WIRING»(ref-466654-S09940782882012042500000)

HINT: After carrying out the repair, check that the fault has been remedied.

1. Ignition off
2. Reinstall the connectors, components etc.
3. Ignition on. Activate the injector that relates to the diagnostic trouble code (DTC). A "click" should be heard when the injector is activated.

PREPARATORY CHECKS

Check and note which adaptation range is incorrect. Scroll through the list of adaptation ranges.

The adaptation value is considered outside normal range if it is lower than 0.85 (engine runs rich) or higher than 1.15 (engine runs lean).

HINT: The ranges consist of a table where the first digit in the name designates the engine speed range and the second the loading range. Range 1.1 designates a case with low engine speed and with low loading. Range 6.6 designates a case with high engine speed and with high loading.

1. Continue Refer to «CHECKING THE SYSTEM»(ref-466654-S24469643382012042500000)

Scheme 55

1. Engine running. Check and compare the calculated air mass with the actual, read-out from mass air flow sensor. Try measuring at different speeds (RPM). HINT: Differences of more than 20 % between the signals indicate a defective mass air flow sensor. Remedy as necessary. NOTE: When replacing mass air flow sensor. Repeat the check to verify that the replacement solved the problem. For more information about current fuel compensation. Refer to «READ-OUT OF TOTAL FUEL COMPENSATION»(ref-466654-S39661062182012042500000) To continue with resetting adaptation. Refer to «RESETTING ADAPTATION»(ref-466654-S29795302642012042500000)

READ-OUT OF TOTAL FUEL COMPENSATION

1. Engine running.
2. Use VIDA or appropriate scan tool for read-out of total fuel compensation at every given moment. HINT: The read-out value shows the short term fuel trims's and the long term fuel trim's total compensation of injection time in real-time. Positive values indicate addition of fuel. Negative values indicate reduction of fuel. Try measuring at different speeds (RPM) with different engine loading. NOTE: Keep in mind that the EVAP-valve's addition of fuel vapors affects the read-out. Squeeze the hose between the EVAP-valve and inlet pipe to minimize the addition of fuel from the EVAP-system.

1. Continue Refer to «RESETTING ADAPTATION»(ref-466654-S29795302642012042500000)

START ADAPTATIONS

Test-drive the vehicle on road and drive a little in different operating situations for 20 minutes, in order to complete as many adaptations as possible.

Check and note if any adaptation range is still incorrect. Scroll through the list of adaptation ranges.

The adaptation value is considered outside normal range if it is lower than 0.85 (engine runs rich) or higher than 1.15 (engine runs lean).

HINT: Also accelerate at full throttle a number of times to implement the adaptations that are not influenced by normal driving.

For adaptation to start, certain conditions must be fulfilled

1. The engine speed is above 600 RPM.
2. Engine temperature between 80-110°C.
3. Fuel trim active = executed.
4. EVAP-valve not active = 0 μs.

HINT: If fuel vaporization is high, the evaporative emission system (EVAP) valve is active for long periods. In this case, it may be necessary to disconnect the hose between the evaporative emission system (EVAP) valve and the EVAP canister.

Are these values OK?

1. YES OKAY: Troubleshooting has been completed.
2. NO Refer to «INFORMATION»(ref-466654-S12197887052012042500000)

CHECKING THE SYSTEM

HINT: If fuel adaptations indicate too rich fuel/air mixture (adaptation value below 1.0) in several adaptation ranges, this indicates a fuel malfunction. The cause may be too high fuel pressure.

To investigate what the problem is due to, perform the following

1. Check that the oil level is between the minimum and maximum markings HINT: Adaptations may show rich fuel/air mixture if several short drives have taken place and the engine oil thus has been contaminated by gasoline.
2. Check the EVAP-valve for leakage. HINT: A leaking valve gives a constant contribution of fuel vapors that affect the adaptations.
3. Engine running.
4. Check the fuel pressure for high fuel pressure.
5. Ignition on.
6. Check the residual pressure with regards to too low residual pressure.

Remedy as necessary.

HINT: If the residual pressure is too low, leaking injection valves may be the cause.

CHECKING ETHANOL CONTENT

HINT: The cause of the symptom and/or diagnostic trouble code may be that the vehicle has been refuelled with incorrect fuel for that vehicle. The fuel system contains fuel with too high ethanol content.

The energy content in ethanol-diluted fuel is lower than in pure gasoline. This means that the control module compensates for the lower energy content, by increasing the injection volume, to be able to reach lambda=1 at the front heated oxygen sensor. This compensation is normally called "Front lambda control slow" or "Lambda integrator", and varies to compensate for the vehicle's status in the form of component spread, small air leaks, wear, etc. The value of this compensation in the ideal case is 1.0 for pure gasoline. Increased ethanol content of the fuel increases the compensation by approx. 0.05 per 10% ethanol dilution.

The control module is designed to handle an ethanol dilution up to 25%. In combination with other deviations from the ideal case, however, lower ethanol content may be enough to cause customer symptoms. This mainly occurs at engine start with cool engine at outdoor temperatures below 0 °C. Then the diagnostic trouble code may also be set for the engine running on too lean mixture.

Note. In a vehicle intended for gasoline, only pure gasoline shall be used. Even if engine start/operation works, other fuel-related components in the vehicle may be damaged by too high ethanol content.

1. Measure the ethanol content of the fuel according to the instructions below. If measured ethanol content is above 25%, then ethanol dilution is the likely cause of the symptom and/or to the diagnostic trouble code being stored. If measured ethanol content is below 25%, symptoms and/or diagnostic trouble code may have been caused by earlier occurrence of incorrect fuel in the system for that vehicle. HINT: Check refuelling history by talking to customer. If nothing indicates incorrect fuel, neither now nor earlier, continue troubleshooting to check other possible causes of faults.
