INJECTION
CHECKS: TURBO PRESSURE
Engine: DT17BTED4
Significant difference in pressure between the two turbochargers:
- Stop the engine.
- Remove the air filter with the two flowmeters.
- Mark the flowmeters "d" and "c".
- Remove both flowmeters.
Refit:
- Flowmeter "d" in place of flowmeter "c".
- Flowmeter "c" in place of flowmeter "d".
Start the engine.
Accelerate to 2500 rpm.
Compare the air flows (mg/stroke) from the two turbochargers:
- If the difference in air flow has changed turbochargers, replace the flowmeter that is faulty.
- If the difference in air flow is coming from the same turbocharger, check the condition of the air inlet
and outlet pipes of this turbocharger: replace or repair the parts that are faulty.
- If no anomaly is detected on the air inlet and outlet pipes of the turbocharger: replace the turbocharger.
