Common Problems with the Engine: An intermittent chuggle or hesitation that can be felt during light acceleration or while cruising at highway speeds with no Check Engine light or no fault codes set may be caused by intermittent operation of the automatic transmission torque converter clutch TCC. The fix for this problem is to replace the TPS sensor.

The OEM intake manifold gasket tends to deteriorate after 60, or so miles in the area that seals the cylinder head coolant passage to the manifold. The fix is to replace the intake manifold gaskets. Intermittent Hesitation While Accelerating or While Cruising Intermittent Misfire While Driving An intermittent misfire that occurs while driving may be caused by a weak coil or worn spark plugs. The distributorless ignition system on the V6 is a waste spark system with three ignition coils.

Each pair of cylinders shares a common ignition coil. This reduces the total number of coils needed. When each coil discharges its high voltage output, it fires two spark plugs simultaneously: one when cylinder is on its compression stroke, and the other when the cylinder is on its exhaust stroke. Only the plug that fires during its compression stroke produces power. Even so, both spark plugs experience roughly twice the electrode wear that spark plugs in other types of ignition systems undergo because the fire every engine revolution rather than every other engine revolution.

Remove and inspect the spark plugs. Replace the spark plugs if any are found to be fouled or worn. The spark plugs should be gapped to. If the spark plugs appear to be okay, inspect the ignition wires. High mileage wires those with overmiles on them can develop increased resistance that may cause the engine to misfire. Replace any wires that are cracked, fit loosely or are damaged.

The Check Engine light should be on, and there should be one or more misfire codes for the cylinders that are misfiring. The last digit on a misfire code indicates the cylinder number. A code P, for example, would tell you cylinder 2 is misfiring. Chances are the misfire is due to a weak ignition coil. The three ignition coils on the engine fire cylinders 6 and 3, 2 and 5, and 1 and 4. If you find misfire codes for any of these paired cylinders, you can be sure the problem is a bad ignition coil and not something else such as lean misfire caused by a bad fuel injector, vacuum leak or EGR leak, or compression misfire due to leaky or sticky valves.

Ignition coils can be replaced separately on the ignition module. But if one coil is bad, it may be a good idea to replace all three on a high mileage engine to prevent similar problems down the road. The crank sensor contains two hall effect sensors that sends two signals to the engine computer. A problem with the sensor or the wiring connection between the sensor and computer can prevent the computer from receiving a cranking signal. The crank sensor has four circuits: a volt reference circuit, a low voltage reference circuit, and two signal output circuits.

NOTE: If the crank sensor is bad and needs to be replaced, a special relearn procedure must be performed after the new sensor has been installed using a GM scan tool or an aftermarket scan tool with similar software. Diagnosing the crank sensor requires looking up the engine wiring diagram for your vehicle, then testing the voltages for the various crank sensor and ignition module circuits to find the fault.This pictorial diagram shows us a physical connection that is much easier to understand in an electrical circuit or system.

An electrical diagram can indicate all the interconnections, indicating their relative positions. The use of this Array can be positively recognized in a production project or in solving electrical problems. This can prevent a lot of damage that even derail electrical plans. The layout facilitates communication between electrical engineers designing electrical circuits and implementing them.

The pictures are also helpful in making repairs.

It shows whether the installation has been appropriately designed and implemented while confirming the safety regulators. A usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device.

This is unlike a schematic diagram, where the arrangement of the components interconnections on the diagram usually does not correspond to the components physical locations in the finished device. A pictorial would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.

They only provide general information and cannot be used to repair or examine a circuit.

The functions of different equipment used within the circuit get presented with the help of a schematic diagram whose symbols generally include vertical and horizontal lines.

However, these lines are known to show the flow of the system rather than its wires. A represents the original and physical layout of electrical interconnections. Wiring on the picture with different symbols shows the exact location of equipment in the whole circuit. Its components are shown by the pictorial to be easily identifiable. They are often photos attached with highly-detailed drawings or labels of the physical components.

What could possibly go wrong? It is a serial data communication bus. It ties together the PCM, the theft deterrent module, the body control module, the dash integration module, the HVAC module and other modules in the car together so they can communicate information to each other. In Park Aves and LeSabres, the Class 2 bus has a ring structure where a single wire for the bus is routed from one module to the next around a ring. In the midsize cars like Regal, Grand Prix, Impala, each module sends a single wire to a central point where all the wires are connected together.

If you cut into a harness to install anything in this car, you will probably cut into one of these lines for the serial bus. If you accidentally connect an serial data line to a hot wire, you may blow two modules or all the modules.

Pure electric car sales were the bulk of that volume with 208.

We also predicted two disappointments for 2016: DS and Volkswagen. VW has launched 3 new nameplates in 2016: the Sportsvan has outsold its rival BMW 2-Series by almost 3-to-1, the Phideon is more of an image booster than a volume model at 800 monthly sales, but the C-Trek is the most promising with 5.

The American SUV brand could easily have been mentioned among our success stories of 2016, as it has sold well over 100. That puts the brand ahead of Cadillac, which did get a mention as one of the most successful brands in China last year. But the reason for holding off and predicting even more success for Jeep in 2017 is the launch of the new generation Compass early this year. The previous generation Compass (and Patriot) have been the best selling import models in China, and starting local production will only add to that success.

Absolutely, but not irrealistic. In its home market, Geely wants Volvo to become a full-blown rival to the German luxury brands Audi, BMW and Mercedes-Benz, but it has a long way to go in terms of volume. This strategy intended to give those local companies the opportunity to learn from their foreign partners and help to the technology to develop their own brands and models.

The best examples of such troubled state-owned automakers are FAW, Chery and SAIC with its Maxus, MG and Roewe brands. Lastly, Shanghai Automotive Industry Corporation has got Joint Ventures with the two largest manufacturers in China: Volkswagen and General Motors, but sales of its own brands Roewe, MG and Maxus were less than 300.

These brands will continue to gain market share at home, at the cost of their competitors who can sit back and rake in the profits by producing cars for their overseas partners.
