C3996 Nissan Frontier OBD Code

OBD/2 C3996 error code description and symptoms.

The input turbine speed sensor detects rotation of the input shaft of the input shaft speed sensor transmission. The computer uses that information, along with the output shaft speed sensor to determine if the transmission is operating according to plan. If the computer detects a difference between the input shaft speed , and the expected output shaft speed, it will adjust transmission pump pressure to prevent clutch disc slip. If adding pressure doesn't solve the problem, it will set a trouble code.

Circuit High Input codes like C3996 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

The scent may C3996 signal oil or coolant leaking from their normally closed-loop systems, or it may indicate dangerous exhaust gases invading your car's interior. Car and truck exhaust contains toxic gases such C3996, so if the inside of your car air suspension rear inflator solenoid output circuit short to ground as if you were standing behind your car, get out and get it fixed. Fight the urge to take a little nap first. So sleepy. That's the carbon monoxide talking, friends. At least open a window on your way to the shop.

Common Causes of Nissan Frontier C3996 OBD2 Code

A common cause of code C3996 is the failure of Air Suspension Rear Inflator Solenoid Output Circuit Short To Ground, but there are several other possible causes as well, such as ;

Faulty Air Flow Meter
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Faulty Variable Camshaft Timing (VCT) position solenoid
Open or short in the VCT circuit

C3996 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
