HYUNDAI TERRACAN LOSING POWER... Hi, I have a 2002 Hyundai terracan that has been losing power. along the highway and straight roads it was fine but on an incline it loses power and now has a job to do 50-60km uphill and is also starting to lose power on flat surfaces mostly getting to 80km. its had a motor replacement 3 months ago and recently I changed the petrol filter, thinking that was the issue. I'm told it could be the petrol pump?? any ideas??

Run the fault codes for an exact diagnosis but from your description of the problem I would be looking at a failing cat converter as it may be blocking up the exhaust system

    what is a cat converter (sorry I am useless with mechanics) & how do I run the fault codes?

  • joanne cash Dec 17, 2014

    ok, I looked that up and the symptoms are all there. just wondering if the noise its started to make is related... its like a high pitched squeeling kind of noise whenever I apply the throttle a bit. coming from right drivers side near wheel it sounds like.

  • Bill Boyd Dec 17, 2014

    the noise may be from a manifold exhaust gasket failure and the exhaust gas is escaping out under pressure. May be if you had the vehicle put on a hoist you could have the noise identified.A squeal may be from a loose ac /power steering drive belt or a failed idler pulley that is making the drive belt slip.But run the codes as well. If there is a problem cat converter/ blown manifold gasket it will show up as a code.

  • Bill Boyd Dec 17, 2014

    fault codes can be read at the vehicle service centre or at a auto zone parts shop. comment with any code numbers found and we may be able to identify what has to be fixed.

    Thank you :)

  • joanne cash Jan 15, 2015

    no fault codes ate showing up using an obd2 reader, maybe its that system itself? cat converter was pulled out and hollowed out as a means of temporary testing and
    now it seems to either be in low 4x4 ( but no light indicating this) or won't select to go to second. mechanic seems to be stumped and just suggests I put it in and he can try a range of different thing from air flow sensor, petrol pump to gears costing
    thousands! I am lost, any suggestions... other than the obvious of finding a new mechanic!

  • Bill Boyd Jan 15, 2015

    the EcM requires the cat converter to work so that the HO2S sensor and the O2 sensor can signal to the ECM so that the fuel/air mixture can be adjusted . Without a functioning cat converter you are just chasing your tail. The suggestion of aan accredited shop that has experience on your vehicle makes sense as I doubt if the current mechanic has enough training to fix the problem

  • joanne cash Jan 15, 2015

    ok thank you :)

SOURCE: head lights dimming and losing power while driving

Next time this happens, pull over and unscrew the gas cap. The vent may be clogged.

Otherwise, your catalytic converter may be failing. It can also clog and hinder engine exhaust.

Good luck !

Shouldn't cost much for 10 minutes work to test fuel pressure & confirm pump condition, but do it when vehicle 's been running for a while, long enough for pump to get heated up.
