What else can I help you with?
What would cause tbi injectors to stay open all the time?
A grounded signal wire from pcm, faulty pcm, or faulty injector are the only possible causes.
Why wont your Toyota 4 runner get power to the injectors?
All of them?Fuse or faulty PCM/ECU.
What if you have code P0205 on a 2001 Chevy Malibu?
P0205 means that the PCM detected a fault in the injector 5 or the wiring to the injector. Could be a bad injector number 5. Maybe the wires to the injectors or the PCM is faulty.
Mercury villager idle?
Idle speed is set by the PCM and is not adjustable. A faulty idle indicates a more complex problem that should be diagnosed.
What does no ccd message received from pcm mean?
The "no CCD message received from PCM" error typically indicates that the Powertrain Control Module (PCM) is not communicating properly with other vehicle systems, particularly the Central Configuration Data (CCD) system. This can result from issues like faulty wiring, a malfunctioning PCM, or problems with the vehicle's communication network. Addressing this error may require diagnostic testing to identify and resolve the underlying issue.
Why do you have no spark on Cylinders 2 and 3 on a 1999 Plymouth voyager replaced PCM and same problem?
replaced ignition coil pack, PCM and spark plugs. No signal comes from the computer to fire plugs 2 and 3, but 1 and 4 are firing nicely. The van WILL NOT start, but -- at times -- it tries. Please help. There is possibility that I bought a faulty PCM with the same problem that I had from the original, but I dunno.
What if voltage regulator in pcm is bad?
If the voltage regulator in the Powertrain Control Module (PCM) is bad, it can lead to inconsistent voltage supply to the PCM and other electronic components in the vehicle. This may result in erratic engine performance, poor fuel efficiency, and malfunctioning sensors or actuators. In severe cases, it could cause complete failure of the PCM. It's important to diagnose and replace a faulty voltage regulator promptly to avoid further damage to the vehicle's electrical system.
Why does 98 regal shut off when turn signal light is activated?
This is due to a bad PCM which needs to be replaced. This is a common problem in these cars. I believe its due the PCM being located in the steering wheel column and just over the years wearing out and breaking due to it vulnerability. Unfortunately a new PCM for a Regal will run you $400 plus. But it's a safety matter and should get fixed. What's happening is a faulty control switch in the PCM that believes you are shutting the ignition off when you are making a turn.
No power to AC Clutch on 1997 Saturn other than typical fuses are there any fuse-able links or hidden fuses?
are you sure the system is still charged?, cause it's controlled by the pcm. If there is low/no pressure the pcm will not turn it on. Or if the high side pressure switch is faulty same condition.....
What is po-207 for code on 99 jeep grand Cherokee?
injector #7 control circuit possible causes , asd relay,injector,wire shorted to ground,faulty pcm.
How do you fix code 52 on a 98' dodge neon?
Code 52 on a 1998 Dodge Neon typically indicates a problem with the powertrain control module (PCM) or the circuit related to it. To fix this, first check the PCM connections for corrosion or damage, ensuring they are clean and secure. If the connections appear fine, you may need to test the PCM itself for proper function, which could involve replacing it if it’s faulty. Additionally, inspect related wiring and sensors for any issues that could affect the PCM's performance.
