I inherited my grandma's 2003 Toyota Camry that sat parked for years. She had bought it new and was meticulous with the maintenance. After doing some research about cars that had sat for an extended period, I did a complete tune up (spark plugs, battery, filters, all the fluids, fresh fuel and even new wiper blades). Once I eventually started it up, it purred like a kitten.

The only problem was an occasional OBD code for a "cylinder 2 misfire." But after about 1,000 miles, it stopped being occasional, and it gradually started running rougher and rougher. I tried everything I could think of to find the problem. Knowing the basic requirements were fuel, air and spark, I tried to narrow down which part was failing. I swapped the spark plugs, coils and fuel injectors between cylinders. I cleared the code and test drove, but the same error code would pop up. I tried different things over and over, and every time within a few miles, the same "cylinder 2 misfire" error would appear. I spent hours pouring over the Chilton manual trying to find anything that could be causing it.

Finally, a buddy offered to look at it with me. We popped the hood and he says, "Walk me through what you've done." I start listing things off, "I moved this spark plug here, that injector to there, this coil pack here..." He thinks for a second, looks in the manual, and once he pointed out my mistake, I felt incredibly stupid. While looking at the engine standing in front of the car, I had counted the cylinders left to right, 1-2-3-4. But, the cylinders are numbered the other direction (4-3-2-1)! They would be 1-2-3-4 left to right while sitting in the car (where I would be while looking through the Chilton manual). Everything I had tried to diagnose cylinder 2 had actually been getting done to cylinder 3! We swapped parts around and, within five minutes, determined it was the coil pack. I ordered the part from RockAuto, problem fixed, the car purred like a kitten again.

Never underestimate the value of a second set of eyes looking at a problem when you are stumped!

Answer below

A new part, the Battery Current Sensor, was quietly added to many new vehicles' charging systems over the last fifteen years or so. Battery current sensors will probably become even more common and complex as car manufacturers add electronic features and try to maximize fuel economy with electric power steering, stop-start engines and other new technology that increases the demand on charging systems.

Vehicle computers use current and sometimes temperature readings from the battery current sensor to adjust alternator output and determine how frequently other diverse systems are allowed to run. That means a corroded, broken or missing battery current sensor can set off a myriad of potentially misleading symptoms.

The engine may hesitate as alternator output is ramped up at the wrong times. The battery might be repeatedly drained. Seemingly unrelated systems such as the AC compressor might stop running as the computer turns off non-critical accessories that share the serpentine belt with the alternator. There might be warning lights and trouble codes indicating the battery and/or charging system is failing.

As can be seen in the photos, battery current sensor designs vary. Sensors that mount directly onto a battery terminal may be exposed to corrosion. Hall-effect style sensors that just form a loop around cables can be accidentally crushed or put on incorrectly when a new battery is installed, cables are replaced or other maintenance is performed.

GM & Ford Hall-Effect Sensors (left) and Audi, Honda & Jeep Terminal Style Battery Sensors

For example, on some GM vehicles the negative battery cable passes through the Hall-effect type battery current sensor. On other GM vehicles, it is the positive cable or cables that go through the sensor. On some engines, the sensor has a fixed mounting point. On other engines, the sensor is just threaded over cable(s) and taped or zip-tied in place. If the right cable(s) are chosen but accidentally threaded through the sensor in the wrong direction, then the computer may be tricked into thinking the battery is being rapidly drained.

See the Battery Current Sensors for specific vehicles by looking under "Electrical" in the RockAuto.com catalog.

This is Miss Lillian. She is a 1987 Cadillac Fleetwood d’ Elegance finished in a Light Amethyst Metallic with Amethyst colored leather interior as well. RockAuto has been the ONLY supplier I have used for all of the cars in my fleet. But, of all my cars, Miss Lillian (I name all of my cars after their original owners) is my absolute favorite.

This Cadillac has 42,000 miles and recently completed an almost 6,000 mile round trip from St. Petersburg, FL to Los Angeles, CA and back to Florida without ever missing a beat! Gosh I love this car. She has entirely new braking, fuel and ignition systems, along with a new suspension. All ordered from RockAuto!
