Yes throttle body heater is the yellow thing on the front. That won't affect running really, only useful on very cold winter mornings.TPS is Throttle Position Sensor, on the bottom of the throttle body. Should be able to feel it if you stick your hand under. ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Ok people updateFriend coming round later with diagnostic equipment Took for a spin was almost like it was overfueling and missing then picking up as you accelerate, had a short run then trip on motorway gritted teeth lol So seems ok when on full chat, makes me think lambda as its getting very hot then and not functioning well when just part throttle when its cooler Place your bets |

update peopletried the link below and have 5v at the plug but when wiring it up and testing the map sensor using the 3 wires it's staying at around 5v there is no voltage change so I guess this is the problem my sensor does not react anything like the video have ordered a second hand one see what happens if it works I'll post up cheers lee http://www.pugaddicts.co.uk/2014/02/map-sensor-testing-with-a-multimeter.html?m=1 |
