I get a POOOA code "cam slow response bank 1" on an 07 VW

Customer Question

I get a POOOA code "cam slow response bank 1" on an 07 VW GTI. TGE CAM, timing chain/belt have been changed. The light engine light flashes when I give it about 2/3 throttle then I loose all power until I let of the gas and give gas again. Could this be the CPS?

Possible causes - Erratic camshaft position due to low oil pressure - Oil flow restriction in the oil passages or the variable camshaft timing (VCT) valve body - Camshaft advance mechanism binding (VCT unit) - Damaged VCT phaser -P000a Description The Powertrain Control Module (PCM) monitors and evaluates the response of the actual position on a target position change. The setpoint and camshaft position are saved at the beginning of a setpoint change. If this change over time is large enough (gradient), the camshaft phasing change is evaluated. If the change after the diagnostic time is smaller than a threshold, a slow response is detected, and if the value is greater, then there is no concern. By detecting a concern, an antibounce counter is incremented otherwise the counter is decremented. If the counter exceeds an adjustable limit, the P000A is set.

no the cps wouldn't do it. But the oil pressure or sludge can do it. Or a defective adjustment valve or wiring can.
