Opel Corsa C - Poor engine running | HELLA

Opel

Opel Corsa C

Model years: 2000 - 2003

Poor engine running, increased emissions.

If there are complaints for these vehicles that the engine is running poorly and exhaust emissions are increased, a possible cause is a bad earth connection of the ECU.

For error analysis, check the earth connection for the engine control unit.

(Control unit housing/earth connection pin 41)

In addition, loosen the earth connection from the earth point and clean; if necessary, replace the earth wire.

Should the malfunction persist, the defect appears to be in the circuit of the engine control unit.

In this case, the engine control unit must be checked, and replaced if necessary.
