Recurring P0335 - Crankshaft Position Sensor “A” Circuit

Fellow Disco Owners,

I have an 04 that I’ve been giving a lot of TLC since purchasing 2 years ago. I’ve replaced all the usual mechanicals, sensors, battery, XYZ switch, CPS sensor (last summer), mass air flow sensor and this winter dropped a new engine in from British Atlantic (which is awesome).

I’ve got about 1k miles on it since the new engine. In the last couple of days I’ve had a couple of instances of a bucking and one time the M&S lights came on and she went into limp mode. The bucking only happened under mild acceleration.

Engine and transmission are strong so my thoughts are it’s electrical/sensor related.

What should I do to diagnose this further? Could it be the CPS again? The new one only has about 2k miles on it.

Any help much appreciated.

Tim.

More info

I should also add that twice I had to crank the starter for what seemed like a minute before it started. Does this also point to the CPS?

Certainly sounds like it. Is your ckps a Bosch? If not, get one; others are unreliable.

I was going to say the same thing.
The Duralast cps I bought at Auto Zone intermittently crapped out on me after 2 months.
Pay the money and replace with a Bosch.

Just ordered the CPS original equipment

Thanks for the replies. I just ordered the $90 CPS Bosch original equipment. I checked my order from last year and it was the $60 version.

I’ll report back with results. So looking forward to installing another one of these - not!

Subscribed. Sometimes I have to crank 2x to get her started. She cranks, but no cigar. Happens once in a while with, what I believe, to be a non-BOSCH CPS.
