Mine is doing it right now too. We put it on the computer and it said that it couldnt reach the Oxygen sensor which is plugged in either on or near the Catalytic Converter. SO im not sure if its the O2 sensor or the Cat yet.

Why is the kb 250 engine warning light flashing continuosly?


the is called the CEL , check engine light , aka. SES or MIL.
in the USA< the EPA mandates that flashing,"OBD2 rules" SAE.org.
it means :
your engine runs so bad, (misfire,etc) that the rich mixture
will burn the CAT up soon.
it says in the operators guide, if you choose to read it.
to drive slow, remove trailers and loads. and get it fixed soon.

this is to avoid the $1000 bill for a new CAT.

88 Izusu Trooper II with 274000 miles Battery warning light comes on when first starting and running- after driving awhile, it goes off and starts charging- also during the warning period- the blower


Sounds like your battery isn't charging properly, first thing to check, is your alternator belt slipping, is it tight enough, if so does it need replacing?

Next the battery, if its over 2 years old it could be on its way out. Does it hold its charge?

Finally, Alternator, is it still providing a charge for the battery? Are all electrical connections good and clean?

Volkswagon Passat 2005 - driving home from work and the handbrake warning light comes on followed by the annoying alarm. Turn slightly left it stops then the ASB warning light comes on followed by the ESP...


This sometimes is triggered by the MAF(Mass Air Flow Sensor), try cleaning it with the highest percent isoproply alcohal first, do not touch the sensor with anything use a big bag to soak it into, or just replace the sensor.

Abs sensor light wont go off my 2005 polo


Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. ANTILOCK systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. The grinding noise could the the ABS pump or your brake pads could to worn to the metal backing and grinding against the brake rotors. I recommend a inspection soon for your safety.

1992 VW Polo 1.3L Coupe: warning light mystery


Bought a very reputable diy service manual for the vehicle, and that plus a bit of thought and nous gave me the cure: no intrinsic problem other than loose relay connections. Went round with the wiring diagrams as guide checking all electrical connections in tight and relays fuses etc all good. Switched on and no problem any more.

By the way, vehicle is 1992 VW Polo - not Fox (which in UK is a variant of the Polo)

1996 POLO - Dash light


Hi

It could be an O2 sensor problem, a catalytic efficiency problem, or even a blocked catalytic converter.

A diagnostic is required to find out which.

Very best regards
