0263 before starting engine?

Recently I've started getting code 0263 "Cylinder Number 1 Contribution/Balance Fault". The odd thing is that this has been detected by the ECU immediately when turning the key to the "pre-start" position. How can the ECU possibly detect that a cylinder isn't "contributing" when the engine isn't even running?

I've had 0301 (cylinder 1 misfire) happen randomly as well, though not lately. The engine never seems to be misfiring when this happens, but my only misfiring experience is on gasoline engines.

I'm wondering if this is more likely a sign of a failing crankshaft position sensor or if it's more likely there really is a problem with cylinder 1 (or others).

( I should probably replace the CPS anyway, just for good measure... replaced practically everything ELSE on the van's engine so far...)

Sorry, I should have been more detailed above. One thing is that the 0263 has been 'detected' only at start up, so far. 0301 has happened only while the engine was running (idling or driving).

What model year, and what scanner is providing the codes?

The 2006 US Powertrain diagnostic manual doesn't use 0301 or 0263.

For misfires, it presents a P0300 as a simple OBD report, then uses 2xxx codes for the individual cylinders:

At that site ( http://www.diysprinter.co.uk/reference/ ) you can download the 2003 (OM612) and 2004 (OM647) manuals, too.

No model year indicated, listed under T1N, so I will assume it's at least a 2006, 13-year-old vehicle?

Logical and systematic diagnostic approach is to begin at the battery. Not trying to be snarky, but "Looking at it", "looks fine", "The tow truck driver installed the battery" (All prior responses) do not constitute or a substitute for battery preventive maintenance. Bypassing this crucial step and you will only be a chasing your tail.

Multiple codes are indicative of ground faults.

Refer to applicable service manual for further details.

Good luck.

True, but there are subtle report number differences between the 2003-and-earlier OM612 and the 2004-2006 OM647.

Annnd... he might be out of the NAFTA area with a much broader selection of engines (and trouble codes)

I could swear I put my van's year in my 'signature' or 'profile'. Anyway, it's 2004. The same codes are read from my Ultragauge and Autel A619.

I have yet to clean up the ground points around the van, but that'll likely be my next task. It's relevant to other possibly related problems too, though was never my top suspect as wiring appeared good from my admittedly inexpert use of a multimeter.

Checking battery and grounds is the first pre-diagnostic step discussed in the service manual. Let's fix your rig! Start with battery terminal post and clamp cleaning. Do you have the tool?

I would not trust those codes unless read by a sprinter conversant scanner (autel 802/808, MBII, Xentry, DAS, Snap-on solus etc). The Sprinter is not 100% OBDII compliant (because its a diesel), so some scanners will report codes improperly.

What are grounds G302 and G100 for for example.
It would be very helpful to identify all of the grounds.

To give an example I tried to move my van with G302 and G100 disconnected. It would not move, the brakes locked the rear wheels up solid.
It started and ran fine.

At least that's my story.

Hi Bill:

I don't have photos of G302 or G100. However, here's a photo of G101 and G102.

2015 schematic shows three of those brown wires feed directly from the ECU.

More about grounds can be found here. http://diysprinter.co.uk/reference/05 service manual.pdf#page305

Considering ECU is grounded to G200, would certainly be a ground point to check for continuity.

In the service manual(s), section 8w-91 has dozens of figures showing where the grounds are located.
This is a case when i would use BOTH the 2003 and 2006 manuals (even for a 2002), since the 2006 manual has more extensive locator figures.
They both have indexes telling you which figures are showing which grounds.

From the 2003 manual, G302 is on Figure 25, and the index even says "engine compartment, left front"

G100 is listed as "underhood, left front" (also fig 25).
Fig 25 shows G100 and G302 being very close to each other near either the left (battery side) front headlight or under the battery tray.
(Bob posted Fig 25 in message #7 of this thread)

In the 2006 manual, those two are on Figure 52 (an example of how many more diagrams are in the 2006 manual)((or dyslexia)).
(and it's the same figure as 2003's Fig 25, so it's not really an additional "win" in this case)

It would be very helpful to identify all of the grounds.

Section 8w-15 is the "ground distribution" section, and the locator index in 8w-91 helps a bit, too.
