Readers ask: How To Diagnose A P0660 Dodge Journey?

What does that mean?

P0660 stands for “Intake Manifold Tuning Valve Control Circuit/Open Bank 1” and indicates that the ECM has detected a general electrical fault or an open electrical situation. This code can be triggered by a mechanical or electrical fault with the intake manifold tuning valve.

What is the severity of this DTC?

It’s a good idea to err on the side of caution when dealing with mechanical parts like the intake manifold tuning valve, especially if it’s an internal part, because the potential for unwanted parts to enter the engine’s combustion chamber exists.

What are some of the symptoms of the code?

Poor engine performance. Loud clicking noise coming from engine bay. Reduced fuel economy. Possible misfire on startup. Reduced engine power. Power range altered are all signs of a P0660 diagnostic code.

What are some of the common causes of the code?

Defective intake manifold (runner) tuning valve. Broken valve parts. Wiring issue (e.g. chafed, cracked, corroded, etc.). Broken electrical connector ECM issue are all possible causes for the P0660 engine code.

What are some P0660 diagnostic and troubleshooting steps?

Diagnostic diagnostic steps are vehicle specific and may require advanced equipment and knowledge to perform accurately. We have included basic steps below, but for specific steps for your vehicle, refer to a vehicle year/make/model/powertrain specific repair guide. The TSB Technical Service Bulletins (TSB) for known issues with the specific vehicle.

Basic Step #1

When the ECM activates a DTC (diagnostic trouble code), it’s a good idea for a DIYer to clear all of the codes; if not, take the vehicle for a long and numerous test drive to see if it/they become active again after a few duty cycles.

Basic Step #3

If you hear clicking noises coming from your intake, this is a good way to see if the intake manifold tuning valve is to blame. If there are no obstructions and the clicking continues, you should replace the valve, as this is most likely the problem.

Basic Step #4

Wiring harnesses can be routed through engine parts and other high-heat areas, so inspect the harness involved with the tuning valve. Engine vibrations can cause chafing/cracking, so keep an eye on them.

Basic Step #5

If you’ve exhausted all other options, check your ECM (Engine Control Module) to see if multiple unrelated codes are currently active or intermittently coming on and off, such as P0303 Cylinder 3 Misfire on a Chrysler 2007 Pacifica P0203 P0660.

How do I fix code P0660?

Bad wiring, connectors, and modules can be repaired or replaced, as can the CAN bus, and if the PCM itself is faulty, it can be replaced.

What is a intake manifold tuning valve control circuit?

The intake manifold tuning valve serves a variety of functions to aid the engine’s performance and drivability, including regulating the pressure between intake plenums and redirecting intake air to a different set of intake runners (or a combination) to alter the flow and possibly the engine’s performance.

What is code P1005?

The P1005 Chrysler code indicates a communication error between the ECU (your car’s onboard computer) and the Manifold Tuning Valve on the intake manifold; if the Manifold Tuning Valve is not replaced, you risk serious engine problems throughout the year.

What can a bad intake manifold runner control cause?

If the intake manifold runner control fails, the vehicle may experience engine performance issues such as misfires, reduced power and acceleration, reduced fuel efficiency, and even stalling.

What is code P2070?

When the P2070 code appears, it means that the engine control unit (ECU) has determined that the intake manifold tuning (IMT) valve is stuck open, based on data from a position sensor built into the tuning valve actuator.

What does the intake manifold control valve do?

Although each carmaker’s design differs, the basic concept entails opening and closing butterfly valves within the intake manifold, which divert airflow and change the length of the runners.

How much does it cost to replace a intake manifold runner control?

How much does it cost to replace an intake manifold runner control? Find out how much it should cost to get your car fixed. The average cost of an intake manifold gasket replacement is between $427 and $558, with labor costs ranging from $334 to $423 and parts costs ranging from $93 to $135.

What is a valve control circuit?

The simplest control circuit for an electric valve is a block of limit switches connected to control buttons and electromagnet relays (starters), with a manual control interlock in most cases.

What are the symptoms of a bad intake manifold?

This article explains three common signs that your intake manifold gasket is failing.

  • Engine Misfires. Engine misfires occur when one or more cylinders in an engine cycle fail to produce combustion.
  • Difficulty Accelerating.
  • Leaking Coolant.

Can I drive my car with a bad intake manifold?

It’s not a good idea to drive your car if it has a bad intake manifold for the following reasons: If you’re losing coolant, your car could overheat; if your car is stalling or performing poorly, you could get into an accident; and if you ignore a minor intake manifold problem, it could turn into a major one.

How do I know if my intake manifold runner control is bad?

Symptoms of a Failing or Bad Intake Manifold Control

  1. Difficulty starting the engine is one of the first signs of a faulty intake manifold runner control.
  2. Engine misfires and a reduction in power, acceleration, and fuel economy.
  3. Check Engine Light illuminates.
