LPG Discussion Forum

I have the software on My laptop for the taxi and I have access to the live data the lpg pressure is roughly 1.5 bar the motor run s fine apart from the P0134 light the reducer is a Brc genius 1500 thanks for your help

Thanks for that the Brc injectors have done over 100,000 miles it had a new vapouriser recently

Hi I have an eml light P0134 upstream 02 sensor replaced the sensor with a new Bosch part the light stayed out for 3 weeks the wiring looks fine the taxi drives fine

Yes it was a broken wire at the back of the engine where it had been chaffing

I actually swapped over the ecus with a known working unity

It has a custom built Ecu and the old original taxi ecu has been removed it’s a dual fuel Ecu that’s switches via a 4 pin round Brc gas switch

It’s got a new Brc genius vapouriser 1500 fitted recently the scs delta gd 16 Ecu has been refurbished as there was a misfire on gas but not on petrol all the gas filters have been changed the issue is the taxi broke down and there is no spark at the coils tried a spark plug in it no code showing up ...

Thanks for that will look into it further

No this is a problem of mine that it broke down suddenly under normal driving conditions.

Crank no start issue have got petrol coming up also lpg no spark at the coil packs but have power at the coil connections , got live data at the crankshaft sensor and cam sensor also have no fault codes or eml lights was thinking maybe a broken wire any ideas

The engine won’t switch between gas & petrol while driving .The engine has to physically be switched off it, while in petrol mode the round Brc switch on the dash the green lights on it flashes continuously but in gas mode they operate normally the taxi runs on Brc injectors and a genius 1500 ...

Brc equipped system with scs delta ecu won’t switch between lpg & petrol while have to switch engine of green lights flashing while on petrol has had a new Ecu & vapouriser and all the filters changed gas pressure reading 1.7 bar any ideas
