Kilps Posted August 2, 2014 Share Posted August 2, 2014 So my girlfriend's dad drives a Nissan Terrano II 2.7 Turbo Diesel and currently the turbo does not seem to be working. I've read that these engines rely mostly on the turbo, which seems to tie up with the current lack of any sensible power. I've read up on how to bridge diagnostic port pins to flash the ECU light to display fault codes, but had no luck. What I've read suggests bridging pins 6 and 7, but pin 6 is empty on this vehicle. I have no idea why. I've had a quick look for the 'missing' wire but it's not anywhere obvious. I've given up on the diagnostics idea for now and decided to have a stare around the engine bay for inspiration instead. The vehicle is Portuguese registered and LEFT HAND DRIVE. There is a sensor attached to the bulkhead on the driver's side (LHS of car; RHS as you look into the engine bay), below the brake fluid reservoir, which looks as though it should have a hose connected to it. There is also a loose hose with a split in the end, which will reach this sensor (but won't stay on because of the split). The hose comes from a little black thing with a few other hoses off it; I'm not sure what this is. My questions: What is this sensor? Should the hose be connected to it? Is this likely to be the source of the apparent turbo problem?? Pictures of said sensor to follow. Quote Link to comment Share on other sites More sharing options...
Benjy Posted August 2, 2014 Share Posted August 2, 2014 Probably the actuator solenoid or MAP Quote Link to comment Share on other sites More sharing options...
Kilps Posted August 2, 2014 Author Share Posted August 2, 2014 I pushed the hose back onto the connector; it was just hanging loose in the engine bay (the other end is attached elsewhere). Quote Link to comment Share on other sites More sharing options...
Kilps Posted August 2, 2014 Author Share Posted August 2, 2014 Probably the actuator solenoid or MAP Thanks mate. I've just googled both of those and none of the pictures look obviously like what I'm looking at. I'm not certain though. Quote Link to comment Share on other sites More sharing options...
Benjy Posted August 2, 2014 Share Posted August 2, 2014 Where does the other end go? Quote Link to comment Share on other sites More sharing options...
Kilps Posted August 2, 2014 Author Share Posted August 2, 2014 Where does the other end go? Stand by, I've just been out to take pictures. They'll be on here in the next five minutes. Quote Link to comment Share on other sites More sharing options...
Kilps Posted August 2, 2014 Author Share Posted August 2, 2014 Long five minutes, but here are the pictures. Red arrow is the sensor, green arrow is the other end of the hose. Any ideas? Quote Link to comment Share on other sites More sharing options...
Kilps Posted August 3, 2014 Author Share Posted August 3, 2014 I put that hose back where it looks like it goes and it's made no difference. Bugger. Quote Link to comment Share on other sites More sharing options...
David P Posted August 3, 2014 Share Posted August 3, 2014 If it's split it won't be doing it's job. Quote Link to comment Share on other sites More sharing options...
Benjy Posted August 3, 2014 Share Posted August 3, 2014 Looks like something to do with brake vacuum. Quote Link to comment Share on other sites More sharing options...
Kilps Posted August 3, 2014 Author Share Posted August 3, 2014 If it's split it won't be doing it's job. No I know. We tried to bodge it with electrical tape and a cable tie, in the absence of a new hose. I had hoped it would work temporarily enough to show that that had been the problem but it made no difference. I guess an actual new hose might do it properly. Quote Link to comment Share on other sites More sharing options...
