Hi all,


Im new to the site and thought I would ask for some advice if you're willing to or know how to help.


On my drive home the it started to regenerate when I hit traffic, I started to pull away and immediately lost all boost, my immediate thought was the turbo had blown but there are no signs of this.


My 2011 Mazda 3 sport (2.2 185bhp) on around the 70000 mile mark with full service history has recently pop up the P2565 code (Turbo charger boost control position sensor A circuit high) after a bit of looking around online it looks as though the turbo vane sensor may have gone. I called a few local garages of which none gave me any answer other than to come in and pay to have it diagnosed which im happy to do.


The cars now acting a bit strange and seems to be constantly regenerating once the engine is warm.


any advice would be greatly appreciated


thank you

 

DTC P2565:00

Guide blade actuator position sensor circuit high input

DETECTION CONDITION
• The PCM monitors input voltage from guide blade actuator position sensor when the ignition switch is ON position. If input voltage is more than 4.90 V, the PCM determines that the guide blade actuator position sensor circuit has malfunction.
Monitoring condition
• Battery voltage:8—20 V
Diagnostic support note
• The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA (mode2) and snapshot data are available.
• The DTC is stored in the PCM memory.
POSSIBLE CAUSE
• Guide blade actuator position sensor connector or terminal malfunction
• PCM connector or terminal malfunction
• Open circuit in wiring harness between guide blade actuator position sensor terminal A and PCM terminal 1AQ
• Guide blade actuator position sensor signal circuit and power supply circuit short to each other
• Short to power supply in wiring harness between guide blade actuator position sensor terminal C and PCM terminal 1BS
• Guide blade actuator position sensor malfunction
• PCM malfunction

Not knowing the ability of aftermarket scan tools, the workshop manual say to monitor VBCV and VBC_POS PIDs using IDS/MMDS

 

Also USA & Canada don't have diesel Mazda's,( Silly but true) so apart from me, and maybe some other foreigners your sh*t out of luck on this forum.

 

thank you for the reply and advice, I should probably try a UK forum then ha.
