hi guys i replaced the standard up pipe on my bugeye. i ordered a greedy one but by mistake i bought the one without the temp sensor hole in it only to find out when i had it fitted the car has a sensor. the problem i have is my engine management light keeps coming on because it's not connected to the exhaust. i have heard that you can connect a resistor up to stop the temp sensor turning the management light on is this true if so does anybody know how thanks in advance guys.

 

Connect a resistor in place of the EGT, or just get the relevant EGT related codes disabled in the ECU.

 

how do you connect it up cheers for the reply

 

just put resistor where the plug was removed on the strut tower, but as you are modding a remap will probably follow so can be disabled in the map, think code is P0545 and P0546 to disable the cel light.

 

do you mean bridge the conection where the sensor plugs in .where can i get a resistor from thanks

 

resistor from maplins, but not sure of value you need, do a search should find out

 

do you just plug the resistor into the connector that the egt sensor would plug into thanks

 

yes it just goes in the egt sensor plug on strut top

 

2.2 KOhms

 

anyone know where i can get one from

 

Sorry to hijack, but what happens if both sensors, egt and O2 are removed? What repercussions will it have for the ECU and feulling?

 

The ECU needs both Lambda sensors to work correctly.......... you can re-map out the P0420 CEL code from the rear lambda if de-catted but the ECU still reads from it.

Thanks for that. I have the Prodrive sportcat and second cat delete, only up-pipe left, and I get the P0420 code. Would you expect the car to not drive as well, maybe a little less smooth with this sensor being 'out of range'

 

CEL P0420 does not change performance in any way, it's just the ECU's way of letting you know the cat is below efficiency (or in your case missing LOL)

Many thanks again! I have been saying this since early 2010, but the remap will remove the CEL once and for all. (cashflow issues have stopped me, although i keep paying out for other little mods!)
