Today I drive the cat & feel delay in all gears . Even in the first gear RPM goes up to 5000. It's seem like transmission faulty. However I am trying to get these sensors dirst.

Thanks for the comments I have cleared this faults & drive the car for two km , Engine warning came back. Even though the codes was clear,gear not shifting to fourth. Speedometer also not working.Now I am trying to replace these sensors and let's see.I checked these connectors no issues found.

Thanks for the info I checked the fault codes ,found P0742 Also found camshaft sensor fault,engine speed sensor fault etc Car has starting delay

I have recently brought an Optra hatchback 2007 model & I noticed gear not shifting from 3rd to fourth. Also engine warning lamp countinusly on .I tried to reset the battery & still same. The car is clocked 180k . Any one can suggest the remedy .
