Unfortunately, engine control units aren’t immune to problems. In fact, it’s not too uncommon for an engine control unit to go bad, and this can cause a whole host of issues for your car. This article will focus on thekey symptomsandcommon causesof a bad engine control unit. We’ll...
2. Physically Check The Engine Control Module This may seem rather obvious, but physical damage may not be apparent until you take a closer look at the module. Use a flashlight to check for signs of damage around the ECU. Remove the wiring harness and make sure the wires aren’t broken,...
A faulty upstream oxygen (O2) sensor can cause the check engine light to come on in Cadillac STS. The oxygen sensor is an important component of the vehicle’s emissions control system, and it monitors the amount of oxygen in the exhaust gases. The engine control module (ECM) uses this i...
Powertrain Control Module (PCM) Your car has the main computer called Powertrain Control Module (PCM). It controls your engine and transmission based on the inputs from various sensors. It's programmed to keep emissions low while maintaining a good balance between fuel economy, performance and re...
Well, but in most (90%) cases it will not fail completely and will not show any symptoms and errors will be thrown. For example in my case, i didn’t have any faults, but i was trying to find out why i have: -Weak torque o low rpms 2-3k rpm, it just feels weak, gets bette...

This article presents the results of research into the causes of the wear of the piston pin mounted in piston bosses by means of a hinge joint and in the connecting rod small end by means of the thermocompression bond. Changes in geometry and in the pin-
creation. Fast-forward 130 years: Dozens of computers control everything from wiper blades and power windows to the internal combustion engine and transmission. Thetwo main computerswe usually worry about are the engine or powertrain control module (ECM or PCM) and the transmission control module ...
The presence of a stored code P0725 means that the powertrain control module (PCM) has detected a circuit malfunction with the engine speed sensor input signal. The engine speed input sensor is sometimes called the transmission input speed sensor and the input speed sensor. This type of code ...
• Perform cylinder leak down and compression testing to identify the cause. • Repair or replace as required. A damaged crankshaft reluctor wheel Replace the crankshaft as required. A damaged crankshaft reluctor wheel can result in different symptoms depending on the severity and location of ...
