Am replacing upstream O2 sensors and cleaning MAF next. Will keep you posted if it clears up. Did you ever find the cause?

SOURCE: s type gearbox fault light keeps coming up on the

There is no gearbox dipstick fitted to this model car. it is the ford 5n box that is ''sealed for life'' If the box is still operating okay the fault may lie in another system and its symptoms could cause a gearbox warning. The best thing would to get the codes read and see what ''pending codes'' are stored along with the current meaning of the gearbox code registered in the system. A jaguar main dealer or specialist will have the equipment to access and read the stored history. hope this helps - good luck.

Car battery light keeps coming on when I come to a stop.. I've recently changed the front lambda sensor as the engine management light came on and it brought up that fault

Plz provide Year+Make+Model of vehicle.

Battery light points to battery or other electrical system malfunction such as the Alternator.

Many Auto Parts stores can test your battery and alternator for free.

I would like to know if both Lambda sensors are the same part number on a 1.0i Vauxhall corsa. 2004 register.

Each sensor is looking for different things so the answer is most likely NO.

My 2003 Terios has failed on high emissions.

First thing I would do is this... Get a can of SEA FOAM and add it to your Fuel. Then drive 100 Miles and have it retested. 90% sure it will pass after cleaning the system.

Lambda sensor

this is a common prob what was the fault code logged ?there are 4 sensors on these cars 2 on each bank upstream and downsteam the issue is the ecm tries to compensate for one bank that is out of limits using the fuel control of the other bank to try and keep overall emissions within limits.this makes diagnosis difficult without proper diagnostic the last count genuine jag. sensors are EXPENSIVE and cheap pattern ones are not that good.advise. find someone with jag diagnostic equip. identify the problem

I have the check engine light on, the engine will start and run at idle when the rpm's are incresed it sound like it has a bit of a miss at about 4000rpm and when throttle is let off the engine stalls...

Probably the fuel filter or pipe is partly blocked. When it runs at idle it has inough fuel. When you push the pedal it cant suply inough fuel and the engine sucks the fuel sistem dry, thats why it is so hard to restart the engine. Ewery time, when you turn on the egnition, the fuel pump in the tank is working only for three or more seconds. Because of blocked fuel pipe, or filter, it takes more time to pump up the fuel in the sistem. Chek the fuel filter and blow the fuel pipe.

Hi Audi A4 1.8 T sport, X reg failed mot on high emissions Front Lambda replaced, and readings still high (running rich) any ideas please

hi this could be a few things but more than likely it is either the MAF sensor or MAP sensor, these things do roughly the same thing, but the MAP also adjusts the timing through the ECM , either one would cause this to "over fuel" and not burn correctly, the starting place would be try the MAF first as this is the common one, make sure spark plugs have been changed as this also will help, if you still get a fail, then try the MAP sensor...hope this helps good luck..

Engine warning light says lean bank 1 low.

generally aftermarket parts are made from the original toyota models so it is doubtful that is the problem. There may be a short in the wires that are causing the sensor to burn out. I would suggest first taking to your local auto parts store and have them scan the ECU for the problem. I hope this helps. Please rate this Thank you

I have a 1997 1.6 carina e. the engine light is on and the computer says it is the lambda sensor. can i get some advice on how to change the sensor and is it worthwhile to get a used one new one is too...

Use aftermarket, it's new. I work at Bosch and make these sensors. It's best to buy new. And they are easily changed with a 22mm wrench. It's a simple unplug the harness from the lambda sensor, and grasp the hex the 22mm and turn left. Get your new one and it will give you better understanding as you change out the old. Very easy and you will be glad you done this.
