P0200 (injector circuit) fault code after clutch start
Posted: Mon, 01 Apr 2019 8:23 +0000Hi
I have a 2012 D4D Hilux that I haven't driven much lately, but it's been running fine when I have driven it.
When I got in it today it wouldn't crank over, so I went to clutch start it down my driveway. It took a couple of goes and I was out on the road by then but it kicked over and made some strange noises, but got running. The check engine light stayed on though, and it went into limp mode, no power at all. I pulled over and it seemed to be idling OK.
I connected to my bluetooth OBDII adaptor and it came up with a P0200 code (injector circuit open). I cleared the fault and the engine light went off, but the engine developed a fierce knocking sound and shake briefly before the engine light went on again and the knock/shake stopped. It then knocked again for a second and returned to a seemingly fine idle.
I then idled it for 20 mins before turning it off and back on, but the same thing happened. I idled it a while longer to then drove it back home in low range to make sure I got up the driveway.
When I got home I disconnected the battery for 10 minutes, during which time I checked that all the plugs in the area were seated OK, and they seemed fine. After 10 minutes I tried again, and got the same symptoms. I let it idle for a while and watched as I cleared the code again and the engine was really swaying when it knocked.
As I am in Wollongong I've put a call in to Baileys and am waiting for a return call from their tech. Could I have fried something in clutch starting it? It seems strange that it idles fine when the fault is present

to avoid this buy a smart charger and never clutch start a modern engine... The alternator will spike to charge the flat battery and fry the electronic systems. Almost a certain despite all the modern technology to protect the system. Sad to hear your expensive problem but hopefully we can all learn from this. It also applies to electric welding (all forms, mig, tig, stick) on a car with the battery connected.
