Td5 Crank Sensor Testing

Td5 Crank Sensor Testing. Need some help please guys one of my customers td5 disco cut out whilst driving has been in to various garages localy and apart from a crank sensor nothing has been changed. Wondering if you can give me some help, i have a discovery 2 td5 2003 which is causing me a bit of grief, it cut out when coming up a hill and would not start.

The values expected from a good ckp sensor are as follows: 2 to 3 volts with engine cranking. Its a w reg defender td5 that drove fine this morning but was then parked up for a few hours and now cranks but wont start.

I.e the injector only injects fuel when the crank is at the correct tdc (compresion not exhaust). The wiring snapped off leaving not much to work with, but i managed to fit a new plug (and new sensor to be on the safe side) using some crimp.

Codes between p0335 and p0338 correspond to crankshaft sensor problems. The ecu knows the crank position from the sensor, but presumably the injectors will only fire fuel in when (1) the ecu tells it to (via electrical signal), and (2) the overhead cam for that injector is in the right position to pressurise it.

Ckp trouble codes if your check engine light is on, then your engine control unit (ecu) has recorded some sort of trouble code. Hi, my td5 engine cranks over but wont fire up, not even trying.

Testing with an ohm meter did not show any problem but moving the wires causes an open circuit. All td5's log these codes.

Below 228 it receives diagnostic pulses only. 2 to 3 volts with engine cranking.

If not then as johnlad says above, it sounds like a crank sensor fault. Below 228 it receives diagnostic pulses only. No faults in the ecu apart from sensors being disconnected.

Hi, My Td5 Engine Cranks Over But Wont Fire Up, Not Even Trying.

The first place to check on a td5 for indeterminate engine errors and odd behaviour is the red plug on the ecu. The values expected from a good ckp sensor are as follows: New fly wheel fitted 3 months ago.

The Part That Still Make Me Skeptical Of The Sensor Was That I Can Read The Engine Rpms While Cranking Using My Scanner.

Just for interest sake the v8 d2 sensors sits at the 8 o clock position on the face of the bellhousing. You're right about ignoring the first 4 codes you receive: The mil lamp is only triggered by crank position sensor (ckp) or throttle position sensors fault.

If You’ve A Nanocom, Using The ‘Inputs Fuelling’ Setting, You Can Get An Engine Rpm Reading When Cranking/Towing.

The reading between the two end pins of the plug of the new cps was measured at 0.9 k ohm. I have a t4 testbook and use this for diag testing. During a recent gearbox change, i made a very common mistake and damaged the wiring connected to the crankshaft position sensor on the bellhousing.

The Manual Says That There Wont Be Any Tach Signal.

All td5's log these codes. My 90 td5 does the same when it gets wet, iether the injector harness or the crank sensor, or with me the three plugs on the fire wall in front of the driver in the engine bay, they shale loose or get wet. I made sure the connector was fully seated, nuts tight and even installed the cover before testing.
