What does this fault code mean?
The engine control module (ECM) compares the actual boost pressure from the turbocharger with the calculated boost pressure. If the actual pressure is too low compared with the calculated pressure while the engine is running, fault code ECM-1507 is set. The fault may lie in the turbo control, in the hoses or in the intake system.
Possible causes
- Air leak in the intake system
- Faulty air temperature sensor at the inlet
- Damaged turbo control motor, turbo control valve or vacuum unit
- Damaged turbocharger
- Leaking, clogged or incorrectly fitted vacuum hoses to the turbocharger or control valve
- Incorrect software in the engine control module on 2005 to 2010 model year vehicles, which can store the code wrongly
What you can do
- 1Inspect the turbocharger and turbo control valve hoses for correct fitting, leaks, damage and blockage
- 2Look for air leaks in the intake system, for example at hoses and clamps, and fix any you find
- 3Check that the connectors to the air temperature sensor and the turbo control valve are tight and free of oxidation
- 4Check that the vacuum unit moves freely and has not seized, and that the EGR valve has not jammed in the open position
- 5On 2005 to 2010 model year vehicles that show the fault now and then, have a workshop check whether the engine control module needs updated software
- 6If the fault remains, have a workshop check the turbocharger and the turbo control valve
Symptoms you may notice1
- Poor performance
What the fault can affect2
- Engine output is limited
- Engine torque is limited
