2003 GMC Sierra 2500 P0120 P2135

GMC Sierra On the 2003 GMC Sierra, the P0120 and P2135  are both pointing to a problem with the throttle position sensor. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If no problems are found, many time a good cleaning can solve this problem. Using some throttle cleaner and a toothbrush and shop rag, try to clean as much build-up from the throttle bore, plate, and plate pivot points. If the cleaning does not solve the problem, then more commonly the throttle body assembly…

1996 Cadillac DeVille P0171 and P0174

1996 Cadillac DeVille P0171 and P0174

Cadillac DeVille On the 1996 Cadillac DeVille, when P0171 and P0174 are set with oxygen sensor codes, more times than not, this is not an oxygen sensor problem. This means the air-fuel mixture is running “lean” and this is what sets the oxygen sensor code. It’s not very common for both upstream oxygen sensors to fail at the same time. So, before condemning the oxygen sensors – First- check the Fuel Filter. Remove the filter and try to blow through it. Any resistance and the Fuel Filter will need to…

2005 Toyota Sequoia C1223 and C1251

Toyota Sequoia On the 2005 Toyota Sequoia, The C1223 is just a general code that only states there is a problem somewhere in the ABS/VSC System. The C1251 narrows that down a bit more and points to the problem being with the ABS Pump Motor. On this vehicle, the pump motor is internal of the Brake Actuator/Skid Control Unit. Some testing will need to be done on the wiring to the unit making sure there are no opens or shorts. And to other items in the ABS/VSC systems. But, more…
