Supported for Chevy Volt 2011-2015 models (Service High Voltage Charging System) issues from poorly designed GM battery coolant sensor or retrofit models (2011-2012).
2011-2015 Chevy Volt
2013-2015 Cadillac ELR
2011-2015 Ampera - (EUROPE)
Overseas customers should validate the coolant level sensor plug is the same as the female pigtail provided by the pictures shown below before ordering if for an Ampera.
This product helps to prevent trips to the dealership when the battery coolant sensor in the Chevy Volt malfunctions and causes a permanent check engine light code to be tripped, which then causes you problems with charging your volt. This can happen even when your coolant level is functional.
GM did a poor job on the design of this particular sensor, and even hitting a large bump can trigger a charging system check engine code. Once you have 'latched' codes present, it requires a reflash of the PCM software. Dealerships charge anywhere from $150-$300 to perform this task if your vehicle is no longer under warranty. This particular product basically creates a constant feedback loop to the ECU with the proper voltage stabilized so that even sensor failure will not trip the code requiring a trip to the dealership.
The only downside is that you must now check the coolant level monthly in your vehicle, which your owners manual recommends anyways. If you do end up running low on coolant the coolant temperature is also monitored, and will throw a code if you do end up running low as documented on the gm-volt forums. Hundreds of Volt owners have done this with good results to date.
An instruction manual is included with the plug set. Velcro is also included to secure the plug/harness inside the engine compartment to existing wires.
This plug is also known as the 'WOT coolant SHVCS defeat plug' on the gm-volt forums. We decided to start offering this product once many Volt owners waited months for product which never did arrive.
Also, we also include a female version of the plug which can cap the existing sensor in the reservoir to prevent any corrosion on the original sensor. This additional plug may replace the factory retrofitted models also where the GM dealerships did a poor job retrofitting the 2011-2012 models after the recall.
Product is crimped with the proper delphi crimp tool and is also soldered to guarantee a solid robust connection for maximum reliability. Factory OEM delphi wire seals are also used to guarantee moisture/rust protection. The bypass resistor used is military grade and will withstand temperatures up to 150c (300F) temperatures, not cheap consumer grade components. Engine bay temperatures may reach up to 250F in some scenarios.

The plug works like magic in our 2011 Volt. I have mechanical skills and was going to make one. Buying your solution was a lot easier. Plus, I won't have to worry about your product failing as they use the right temp rated materials and are both crimped and soldered. -- Matt
