Hi folks,

I have 307 1.4i 8v engine TU3JP
Everything running fine until Saturday just gone, when car suddenly lost revs and power above 2250rpm as if a rev limiter had kicked in and wont rev above that, it tries. No warning lights on dashboard, engine management light was unlit and there was no info on the display panel at this point.
When I got the car home I plugged in my little ELM327 to read any codes if present, it came up with:
P0500 - Powertrain, Vehicle Speed Sensor.
I left the car alone for the rest of the day and went looking things up on the interweb.
Sunday morning I further investigated the car, I drove to the end of the road and back 1/4mile to see if the speedo was working, it was working ok, still suffering the same revving issue but this time things got worse was misfiring terribly and the Engine Management light was flashing with an accompanying message saying 'Catalytic Converter Fault', subsequent error code reading via Torque Pro revealed
P0300 - Powertrain, Random/Multiple Cylinder Misfire detected.
P0500 - Powertrain, Vehicle Speed Sensor.
I have not wanted to start the car since, in fear of doing any serious damage to anything.

Im at a loss to know what to do next. Could this mean physical engine damage? or is it more likely just to be sensor issues? Hoping its not something like the timing belt gone, although I'll try and inspect that tomorrow.

Any help or suggestions welcome.
as i type this Im looking down the forum's planet map for a member with the diagnostic kit that may be able to help close to Birmingham B32

Regards
Simon

Have sent you a PM.

Update

Firstly,
Thanks to forum member Phil McNeil for coming over to mine on Thursday evening with his PeugeotPlanet software in an attempt to diagnose the culprit that is causing my current engine running issue. Hope you enjoyed your 'chippy tea' when you got home.

I checked the timing belt before Phil arrived and all looked good. (kind of knew it wasnt a timing belt problem but it doesnt do any harm in checking it's condition from time to time)
Checked spark plugs too, they looked fine also, light tan in colour, no sign of oil contamination or bad mixture.

So today I have removed the speed sensor from the diff housing and taken note of its numbers etc. Wiring and connection looked to be in good order.

If it helps any, here is a short video with audio I took today of the issue. Note the odd revving is not caused by me jiggling throttle, i hold throttle constant and it does it it's self.

Resolved

Hi folks.

Firstly, apologies for not responding after it was resolved last year but big life issues got in the way, but hey Im still alive.

I took it to a local independent pug specialist who knew what the issue was instantly without the need for diagnostics - a failed 'Throttle Position Sensor'.
So for a shade less than £20 had me a new one in hand and fitted it myself.

Car has been running fine since then.


Many thanks for the help and input.

Kind regards
Simon

Good on you for being decent enough after all this time to feed that valuable info into the Forum. That is what these forums are for, to build up the knowledge of these and other cars so that those that can are able to fix their cars without having to pay the sometimes extortionate fees some garages charge and don't always fix. Did the pug specialist charge you much?
Glad your problems are resolved too by the way.
