Advice fitting accelerator pedal needed.

Post by elsid » Sat Oct 05, 2019 10:29 am

My Corsa E 1.0T is suffering with the 'engine power is reduced' problem and I used a ODB2 device which gives fault code P2138 Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation. It suffers this mainly on cold damp mornings and has been relativity trouble free during the summer months. I have purchased a new accelerator pedal part number 13305805 and could do with some advice on how best to fit it. I read somewhere you may need to disconnect the battery so that the ECU re-learns the pedal setting but I think that was for the Corsa D. Any advice appreciated.

A work colleague recommended his sons garage so I took a chance and the mechanic connected it to a diagnostic gadget for an hour and charged £50. He didn't do any other checks that I could see or look for loose wires on the engine. Even though it was cold and raining heavily, on this occasion my car did not go into 'engine on reduced power', but then it is an intermittent fault and the mechanic said he could not replicate it. So all he found was the same as my own ODB2. He said he had deleted the stored fault codes and re-calibrated the the accelerator and if it happens again it will need a new accelerator pedal. He also said a new version of the pedal has been released to stop the problem and it will need recalibrating. However I have also heard they are 'plug and play' and do not need re-calibration, so I will have to ask the Vauxhall dealer which is correct. I still have no explanation as to why it only happens when the engine is cold; when fully warmed up the engine runs normally for the rest of the day, which is why I am suspicious that it may not be the pedal so sent the pedal back and got a refund.

I found this video on YouTube, looks helpful.

You should have replaced the pedal as clearly there is a fault as VX modified the part

Here is my experience replacing a faulty accelerator pedal with fault code P2138.
For some reason this message box rotated the image and will not allow me to correct it, however the image appears correctly if you right click it and select view image.

The Sandy Anderson video was a big help so take a look first then remove the light switch although there is no need to unplug it. Unlike in the video, my Corsa had a large empty plastic tray completely obscuring the right hand bolt so I used a long 20mm masonry drill I just happened to have to drill a hole in the tray and gain access. This allowed me to use a 3/8ths socket extension with a 10mm socket to remove the bolts. At first I could not remove the bolts until I realised they were longer than expected and I just had to keep turning until they came out. Disconnect the power plug on top of the accelerator pedal, push the pedal up to lift it off the lower retaining lug and it should come out easily. Reverse the procedure to fit the new pedal. Before I replaced the pedal the engine light was showing on the dash and I had fault code P2138 on my ODB2 phone app scanner, both disappeared after the new pedal was fitted.

Vauxhall wanted £155 for the pedal, although they did offer 10% off when I asked for a disscount. They told me the pedal is 'plug and play' so no need to re-calibrate. In the end I got lucky and purchased a brand new pedal off eBay for £20 + postage.

A few more photos of the finished repair, the light switch and 3/8ths socket extension bars need to reach the bolts.
Note masking tape on top left bolt used to hold 10mm socket in place.

Don't suppose you measured the length of the socket extension re last pic
