He's correct in that the sienna catalyst is integral with the exhaust manifold. That is done by the manufacturer to ensure that the catalyst reaches operating temperature as quickly as possible. It's not true of all cars so your friends...
The battery you installed is a 12 volt battery and although the cranking amps rating of the battery you have applies to a higher temperature (marine environments are typically relatively warm environments) at 1,000 MCA (marine cranking amps), that is...
Hi Samantha. Thanks for sending us a question tonight. Braking hard is very "hard" on vehicle suspension, steering and brake system components, so it's actually kind of common for a car to jerk a bit when you brake hard. However,...
All the codes are for too high of voltage from sensors and indicate a computer reference voltage of 5 volts are too high or there is a short in wiring. You will need to have the computer codes pinpoint tests...
A possibility is the neutral start safety switch is defective. Car designers place that switch in the starting circuit to prevent the car from being started while the car is in gear. Starts in Park or Neutral are the only...
Check the fluid level (and fluid condition) in the transmission to be sure the fluid level is not too high or too low. The jerking could be transmission or engine related. If the noise is coming from the transmission, and...
Hello and thank you for contacting YourMechanic. With the engine only revving up and the transmission is not moving in any direction forward or reverse, then there is a problem with the pump in the transmission. The transmission oil pump...
Most people don't know this but your steering and your brake booster have a lot to do with each other. Often times if you pump the brakes while trying to turn you will experience stiffness. If this is the problem...
Hi There, You are likely correct in that if the leak is not coming from the high pressure line, it may be leaking from the return lines. I would suggest having a professional from YourMechanic come to your location to...
Hello there! This sounds like a malfunctioning power steering pump, which is common for your vehicle. If this is the case, the location of the leak makes sense because the power steering pump is located on the passenger front side...
Power to the horn is interrupted due to a wiring issue or the horn itself is not functioning. You can use a voltmeter to test for battery voltage at the horn terminal. If there is battery voltage, and yet the...
The problem is inside the transmission with pressures or shift solenoids and will need to have a transmission expert test and diagnose it to isolate the cause.
Hi Corey. Thanks for contacting us today. The red lightning bolt warning light indicates an issue with the charging system. In order to download the codes, you'll need a professional digital scanner. If you'd like to have one of our...
As far as deactivating the built-in immobilizer, there is no user accessible option to do that. A Hyundai dealer might have access to a control interface to modify the immobilizer but then anything the dealer does will have to be...
Sounds like you have taken a lot of the right steps, but lets go back to the beginning. A P0505 code doesn't necessarily mean the IAC is bad. Specifically it says that there is a malfunction in the idle control...
If you are reusing your old fluid you are defeating the purpose of changing the filter. I would only say this is ok if the ATF (automatic transmission fluid) was already spotlessly clean. If not, I recommend having a ATF...
Hi Patrice. Thanks to contacting us today. One thing that might be causing this issue - that was not mentioned is the brake switch. This component is a safety system that will lock the key in the ignition and the...
The fan for a radiator supplies airflow while the car is sitting at a stop, generally when I see a car that is slowly overheating I check the fluid level to make sure it's full and that the water pump...
Although I have seen the gearboxes leak in the field, the more common place they tend to leak is the power steering lines themselves, and occasionally from the pumps. I would start by cleaning off all the surfaced of the...
The best way to locate a fluid leak of any kind is to first clean the entire area that the leak is suspected to be coming from. Then allow time for the area to dry or use compressed air to...
