General Information Introduction •
The new Mazda MPV facelift has now been further enhanced to ensure it continues to meet the demands of European customers looking for a vehicle that is safe, fun to be in and drive, with lots of space and flexibility. At the same t ime, full compliance with EOBD regulations of the RF-T engine models and the inclusion of a Karakuri seat version all improve on what was already a successful formula.

Emission system (RF)
Emission System (RF) Features •
An EGR (Exhaust Gas Recirculation) valve position sensor has been added to allow compliance with EOBD regulations
EGR valve position sensor •
The EGRVP (EGR Valve Position) sensor is located at the EGR valve and detects its position by a sliding contact potentiometer. When the EGR valve opens the resistance of the potentiometer rises. The sensor supplies the PCM with an analogue voltage signal between 0…5 V.

EGRVP sensor

PCM
The signal of the EGRVP sensor serves to detect a malfunction of the EGR valve, i.e. the PCM (Powertrain Control Module) permanently compares the sensor information with the actual EGR amount. The amount of recirculated exhaust gas is determined from the difference between target intake air amount (calculated from the engine speed and the fuel injection amount) and the actual intake air amount detected by the MAF (Mass Air Flow) sensor.

On-board diagnostic system Diagnostic test modes •
To meet EOBD regulations, the following diagnostic test modes have been adopted:
Diagnostic test mode Mode 01 Mode 02 Mode 03 Mode 04 Mode 07 Mode 09
Item Sending diagnostic data (PID data monitor/On-board system readiness test) Sending freeze frame data Sending emission-related malfunction code (DTC) Clearing/resetting emission-related malfunction information Sending continuous monitoring system test results (pending code) Request vehicle information
Recording of continuous monitoring system test results •
These appear when a problem is detected in a monitored system
1-drive cycle type
–
If any problems are detected in the first drive cycle, pending codes will be stored in the PCM memory, as well as DTCs.
–
After pending codes are stored, if the PCM determines that the system is normal in any future drive cycle, the PCM deletes the pending codes.
2-drive cycle type
–
The code for a failed system is stored in the PCM memory in the first drive cycle. If the problem is not found in the second drive cycle, the PCM determines that the system returned to normal or the problem was mistakenly detected, and deletes the pending code. If the problem is found in the second drive cycle too, the PCM determines that the system has failed, and stores the pending codes, and the DTCs.
–
After pending codes are stored, if the PCM determines that the system is normal in any future drive cycle, the PCM deletes the pending codes.

On-board diagnostic system (continued) OBD drive mode •
With the addition of system monitors for EOBD, it is now necessary to carry out the OBD Drive Mode to confirm the absence of the below DTCs:
– – – – – –
P0101: MAF sensor circuit range/performance problem P0106: Boost sensor circuit range/performance problem P0401: EGR flow insufficient detected P0402: EGR flow excessive detected P0404: EGR valve stuck P2227: BARO sensor circuit range/performance problem
To conduct the OBD Drive Mode: 1. Warm up the engine to normal operating temperature. 2. Verify all accessory loads (A/C, headlights, blower fan, rear window defroster) are off. 3. Drive the vehicle five times in the driving mode indicated in the figure on a road with a 0% gradient. 4. Stop the vehicle. 5. Verify no DTCs are present.
