OBD-II Code
P1335
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$180–$2,800
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$180 (CKP sensor DIY) to $2,800 (CKP + timing chain on a QR25).
P1335 is Nissan-specific: Crankshaft Position Sensor (REF) Intermittent — the ECM lost the reference signal from the CKP sensor briefly enough to set the code but not long enough to stall the engine permanently.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P1335 is Nissan-specific
Crankshaft Position Sensor (REF) Intermittent — the ECM lost the reference signal from the CKP sensor briefly enough to set the code but not long enough to stall the engine permanently. The Nissan CKP is typically a Hall-effect sensor reading a toothed reluctor on the crank or flywheel, outputting a 0-5V digital signal at cranking and running speeds. Cheapest-first ladder: scan live data and watch CKP RPM signal during cranking and at idle (should be a clean 0-5V Hall pulse train, no dropouts; some earlier VR sensors run 0.5-1.5V AC at cranking rising to 3-5V AC at idle). Inspect the sensor connector for oil contamination — Nissan CKPs sit near the bellhousing and get oil-misted from rear main seal weeps, which migrates into the connector and corrodes the pins. Wiggle-test the harness while monitoring live data. Pull the sensor, inspect the tip for metal shavings (a magnetic Hall sensor pulls steel debris from a worn reluctor), measure air gap if adjustable, and check the reluctor for chipped teeth. Don't condemn the ECM before you've verified the CKP signal at the ECM connector pin — Nissan ECMs are rarely the failure here.

- 2002-2008Altima/Maxima/Murano with the VQ35DE is the classic P1335 case — the CKP sensor degrades with heat cycles and causes a rolling-stall condition where the engine cuts out for half a second and restarts itself, usually at low RPM or coming to a stop. Nissan issued multiple bulletins on CKP/CMP sensor failures across the VQ family.
- 2005-2012Pathfinder/Frontier/Xterra VQ40DE shows identical symptoms plus heat-soak failure where the code only sets after 20-30 minutes of driving and clears on cool-down.
- 2002-2006Sentra/SE-R with the QR25DE throws P1335 from CKP failure tied to the same timing-chain stretch that pulls the reluctor wheel out of alignment — confirm chain stretch with a cam-vs-crank scope capture before just replacing the sensor.
- 1999-2004Frontier VG33E V6 throws P1335 from the optical distributor pickup degrading rather than a separate CKP.
