Parts for your 2013 Isuzu D-max-Crank angle sensor

2013 Isuzu D‑MAX crank angle sensor: purpose, service tips and replacement

Based on technical sources, the 2013 Isuzu D‑MAX is fitted with a crank angle sensor (also called a crankshaft position sensor). The Isuzu D‑MAX 2012–2016 Workshop/Service Manual (Engine Control System) lists DTCs P0335/P0336 for the crankshaft position sensor circuit, and the Isuzu 4JJ1/4JK1 engine manuals illustrate the sensor mounted to the engine block reading a toothed wheel on the crankshaft/flywheel. Bosch EDC17 common‑rail diesel management used on these engines also requires both crank and cam signals for injection and timing control. So yes—this part is present and essential on the 2013 D‑MAX.

The crank angle sensor on a 2013 Isuzu D‑MAX tells the ECU exactly where the crank is in its rotation and how fast it’s spinning. That precise timing data lets the ECU fire injectors at the right moment, stabilise idle, and manage starting, power and emissions. If the signal drops out or gets noisy, the ute can be hard to start, stall, run rough, or even refuse to fire.

It’s not a routine replacement item, but it pays to give it some love during servicing. Under the bonnet, a quick visual once‑over of the sensor body and connector for oil contamination, heat damage, or chafed wiring is smart. If you’re chasing a no‑start or intermittent cut‑out with an engine light, scan for codes—P0335/P0336 are the big clues. A failing sensor can also set a crank/cam correlation fault.

• Common symptoms: extended crank, sudden stall, limp‑home, erratic tacho, poor fuel economy, and the MIL on.
• Basic checks: secure connector, clean pins, intact harness, and no metal swarf stuck to the magnetic tip (if removed).
• Replacement tips: disconnect the battery, allow the engine to cool, replace the O‑ring if fitted, and lightly oil it before install. Don’t overtighten the retaining bolt—follow workshop specs.

Most D‑MAX models don’t need coding for a new crank angle sensor, clear the codes, then perform a proper warm‑up and drive cycle. Some scan tools offer a “CKP learn/idle learn”—follow the workshop manual if prompted. Use a quality OEM‑equivalent sensor, cheap copies can cause ghost faults. If wiring is brittle or oil‑soaked, consider a loom repair at the same time. When in doubt, an auto sparky with a scope can confirm signal quality in minutes, saving guesswork and parts darts.

Popular questions

Where is the crank angle sensor on a 2013 Isuzu D‑MAX?
On 4JJ1/4JK1 engines it’s mounted to the engine block and reads a toothed reluctor on the crankshaft or flywheel. Access varies by model, it’s usually reached from underneath or low in the bay. A workshop manual diagram helps pinpoint the exact spot.

What causes crank angle sensor faults on these utes?
Heat, vibration, oil contamination, damaged wiring, or a sensor tip covered in metal particles can all degrade the signal. Less commonly, a cracked reluctor/toothed wheel or widened sensor gap can trigger P0335/P0336.

Should it be replaced as part of regular servicing?
No, it’s not a scheduled item. Treat it as inspect-and-test: check wiring and connectors during services and only replace the sensor if diagnosed faulty. Always clear codes and road‑test after repair.
