What is po660?
Error Code P0660 is defined as Intake Manifold Tuning Valve Control Circuit/Open Bank 1. This means there’s a problem with the bank 1 of the engine intake manifold turning valve control circuit, which is usually caused by damaged wires or defective PCM.
What does Bank 1 mean in intake manifold tuning?
Bank 1 refers to the bank of the engine which contains the number one cylinder. Intake manifold tuning is used to restrict and control intake air as it enters individual manifold ports. Not only is the volume of intake air regulated by the IMT, a swirling motion is also created.
What does trouble code p0661 mean on an intake manifold?
P0661 is the trouble code identified as “Intake Manifold Tuning Valve Control Circuit Low Bank 1” and this indicates that the ECM has detected too low of electrical reading from the valve on bank #1.
When do I set the OBDII code for the intake manifold?
The Powertrain Control Module ( PCM) continuously monitor the Intake Manifold Tuning Valve (IMTV) system during Key ON engine OFF or key ON engine running self-test. The PCM sets the OBDII code when the signal on is more or less than the expected calibrated range. Need more information on how to fix the P0661 code?
What causes an intake manifold tuning valve to malfunction?
This code can be triggered by either a mechanical or electrical fault with the intake manifold tuning valve. If you are located in an area susceptible to extreme cold weather, it can cause the valve to malfunction and not rotate fluently according to the ECM’s desires. A GM intake manifold tuning valve:

How does an intake manifold turn valve control circuit work?
When an intake manifold turning valve control circuit experiences an error, it will store a trouble code and activate the Check Engine light. For some vehicle models, they require multiple drive cycles (up to 8) with a failure to activate the Check Engine light, while other activate the light right from the initial failure.
