Thanks Smith Posted on Aug 15, 2009 What year is it? Broken, disconnected, shorted, or open electrical circuits, broken, disconnected, or corroded electrical wiring or connectors could also be causes of this code being stored. Many times the problem can be identified visually. Please remember to rate this answer. If the circuit tests normal, replace the engine control module. The information contained on this site is presented for informational purposes only.
Also, depending on your state, this code may fail you for emissions inspection. If this is the case, it could be an unexpected, very expensive engine repair for the customer. If the Manifold Flow Valve blades are seized in the intake manifold, the manifold will have to be replaced However this code can sometimes have a very easy fix and if you are lucky you may find that it is caused by a split vacuum hose connecting to the actuator. The shutter will be in the closed position not allowing airflow blend to occur in the intake manifold. Cabin noise is mostly absent, thanks to triple-seal doors, a laminated windshield, and hydraulic engine mounts. How serious is the P2070 code? When the tuning valve gets stuck open, it is possible that the engine may not perform optimally.
Mar 01, 2015 sounds like you have to do a cable adjustment. What repairs can fix the P2070 code? We are not responsible for any actions you take on your vehicle. This may cause engine failure and will ultimately require engine replacement. Not only that autozonded scans may show the wrong code. The Chevrolet Cruze is all-new for 2011, and is now the resident compact sedan in the Chevy lineup, replacing the Cobalt. Cabin noise is mostly absent, thanks to triple-seal doors, a laminated windshield, and hydraulic engine mounts.
It may be possible for carbon or oil sludge to build up in the intake manifold and cause the valve to become stuck, or bind. From what I understand the cel should not be lit. Four distinct trim levels are offered, and power comes from one of two 4-cylinder engines--a normally aspirated 1. Rather then guessing an just replacing parts. A leak in the vacuum system will set the code and I suggest you check this out first as a potential cause.
What is the recommended method of cleaning the carbon from this component? For the electronically controlled system you will need a scan tool to be able to see if the position sensor is working correctly. It is possible that you may notice some slight power loss from the engine. The P2076 diagnostic trouble code should be addressed immediately. The Cruze shares its attractive styling cues with other Chevy offerings, notably the Malibu. A 6-speed manual and automatic transmission are offered, as are a host of interior amenities and safety features.
Symptoms Symptoms may include a rough engine idle, an engine surge, a slight reduction in low end engine torque, a code will be stored and a service engine soon lamp may be illuminated. What are the symptoms of the P2070 code? The direct-injection engine delivers 148 ft-lb of torque at 1,850 rpm, and Chevrolet estimates it can deliver 40mpg on the highway. The distinctive split front grille is found on other new cars in the company portfolio. A diagnostic trouble code is normally considered serious when it causes driveability issues or a change in performance. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. If the circuit tests normal, replace the engine control module.
Common Misdiagnosis Technicians report that the intake manifold tuning valve is frequently replaced in error when excessive carbon deposits are at the root of the problem and vice-versa. However, if there are mass airflow codes or barometric pressure sensor codes present; either one of those sensors could have contributed to this code being stored as well. Collect any available freeze frame data as well. Trouble code P2070 sets when the engine management computer detects that the intake manifold tuning valve has not moved from the open position when commanded to close. There is no monitor input to the Powertrain Control Module with this system to indicate shutter position. Posted on Aug 15, 2009 I found this about po660 and hope it helps: Intake Manifold Tuning Valve circuit Malfunction.
Battery voltage is between 9. The valve is situated on the inlet manifold on your engine. Is it near the air intake of the manifold? Above approximately 2600 rpm or higher, the motorized unit will be energized. The second cause is due to carbon deposits which form on the manifold tuning valve. Styling is in line with the company's other offerings, which means the Cruze already has a familiar feel to it.
Ambient temperature is greater than -9. YourMechanic offers certified mechanics who will come to your home or office to diagnose and repair your vehicle. What causes the P2076 code? Is it near the air intake of the manifold? Styling is in line with the company's other offerings, which means the Cruze already has a familiar feel to it. . Oftentimes when this code sets, you will find the plastic bushing nowhere to be found and the actuator rod is hanging loose and not controlling the tuning valve. Devices that control charge motion are commonly called Intake Manifold Runner Control, Swirl Control Valve, and Charge Motion Control Valve.
The test fails when the signal on the monitor pin is more or less than an the expected calibrated range. If the circuit tests normal, replace the engine control module. Enter the 5 character trouble codes in the search box and submit the search. A 6-speed manual and automatic transmission are offered, as are a host of interior amenities and safety. Immediate attention to the P2076 diagnostic trouble code is required in order to prevent engine failure due to damaged engine components. And with an available 138-hp turbocharged engine with direct injection, it's possible to achieve excellent fuel economy with a sporty feel.
