2011 Isuzu D‑Max Crank Angle Sensor
Technical sources confirm the 2011 Isuzu D‑Max (2.5 4JK1 and 3.0 4JJ1 common‑rail diesels) is fitted with a crankshaft position sensor, commonly called a crank angle sensor. References include: Isuzu D‑Max/Colorado Workshop Manual (2011–2012) – Engine Control System, DTC P0335–P0339 (Crankshaft Position Sensor), Isuzu 4JJ1/4JK1 Engine Service Manual – Engine Electrical, and general diesel control references such as Bosch EDC16/EDC17 system guides used on these engines.
On this D‑Max, the crank angle sensor is the ECU’s timekeeper. It reads a toothed wheel on the crank to tell the computer exactly where the pistons are and how fast they’re spinning. That signal lets the ECU fire the injectors at the right moment, manage rail pressure, and coordinate with the cam sensor for smooth starting and clean combustion. If it drops out, the ute can be a no‑start, go into limp, or feel rough as guts on the road.
It’s not a scheduled service item, but it’s worth a look during major services, especially on high‑kilometre vehicles that see heat, dust, mud and corrugations. A quick visual under the bonnet for oil leaks onto the sensor area, cracked wiring insulation, or loose connectors can save a headache later.
- Common symptoms of trouble: hard or no start (hot or cold), intermittent stalling, erratic tacho, sluggish performance, and engine light with codes like P0335/P0336.
- Basic checks: scan for codes, inspect the plug and loom for chafe near the front timing cover, confirm clean battery and earths, and ensure no metal debris stuck to a magnetic sensor tip.
Replacement is straightforward for a competent DIYer, but most owners are happy to let a workshop handle it.
- Disconnect the battery and let the ECU power down.
- Locate the sensor at the front timing case (near the crank pulley on most 4JJ1/4JK1 setups).
- Unplug, remove the retaining bolt(s), swap the sensor with a genuine or quality OEM‑equivalent, lightly oil the O‑ring, and refit.
- Torque to the workshop spec, reconnect, clear codes, and verify crank and cam sync on a scan tool.
There’s no real “maintenance” beyond keeping connectors clean and secure. If the sensor is failing, replacement is the fix—don’t chase your tail. Using genuine spec parts and checking harness routing to avoid rubbing on brackets will keep the D‑Max happy over long Kiwi and Aussie kilometres.
Popular questions
Where is the crank angle sensor on a 2011 Isuzu D‑Max?
On most 4JJ1/4JK1 engines it’s mounted at the front timing case, reading a reluctor on the crank. Access is from the front of the engine bay, a torch and small ratchet make life easier.
Can a bad crank angle sensor cause no‑start when hot?
Yes. Heat‑soak failures are common—once the sensor cools, it can restart. A scan showing P0335/P0336 and a clean cam sensor signal points strongly at the crank sensor.
Should the crank angle sensor be replaced as preventative maintenance?
Generally, no. It’s replaced on condition. During servicing, check wiring, connectors, and for oil leaks. If symptoms show or codes store, test and replace promptly.
