Check for oil leak(s) underneath the car...this might be messing up your electrical connections. According to my 1984-1994 Tempo/Topaz Repair Manual. It is the Exhaust Gas Recircuation (EGR)valve. A Malfunctioning EGR valve can cause 1 or more of the folloming syptoms: 1) Detonation, 2) rough idle or stalls on deceleration. 3) Hesitation or surge. 4)Abnromally low power at wide open throttle. My 94 Topaz has the same porblem, expect I replaced my EGR valve and it still acts up. So I'm check ing the other parts of that system. The EGR Transducer, and the EGR Vacuum Regulator (EVR). Have your fuel injectors cleaned. About $100 at a garage. When they get hot they gum up because of deposits. Check the distributor, that was the problem with mine, I needed a new one
It's a little black box mounted onto the throttle body.
if havent checked already look at the throttle body behind the butterfly valve and see if you have a carbon build up which in turn screws with throttle position sensor giving it a mis-reading
the reason the throttle would be sticking on your focus is that it (the actual unit) could be dirty. or the throttle cable could have dirt in its casing. what you need too do is remove the throttle cable and spray engine degreaser in the casing and hang it up too let the dirt and grime drip from it. be sure to use wd-40 to relubricate the cable. now as of the throttle body do the same thing. but use a non abrasive cloth and wipe the unit clean. make sure there is no dirt in any small cracks or crevises.
P1614 - Ignition key/engine control module malfunction
Control, dependency, compliance, and cooperation.
The throttle position sensor tells the engine control module what you are doing with the throttle as you drive. If you let your foot off of the accelerator pedal the throttle position sensor sends that information to the engine control module and the engine will receive less fuel and it will lose rpm.
It is on because the engine computer has detected a malfunction with the electronic throttle control system.
A Throttle is the fuel control that controls the mixture of fuel and air and the rate of flow into the engine.
It is called a throttle body control module. It is in the engine compartment on the top of the engine.
The throttle body is controlled by the engine computer, which is located on the firewall.
No such part. The computer actuates the throttle plate to control engine speed.
Yes it had a throttle body to control the amount of air getting into the engine.
The throttle position sensor determines the amount of throttle used when the engine is running at various speeds. If the sensor is faulty, it can be replaced by ordering a new part.
on throttle body
Check fuse(s) and wiring. Could also be the control module, an electronic marvel that cannot be repaired only replaced. The throttle link between the gas pedal and the engine could also be broken.
Throttle body
Yes it can. The engine is exactly the same except for the throttle body an intake. Just use the ones on the old engine.
