That resistance should vary according to pedal position (low resistance without pressing pedal, increasing to higher resistance when fully pressed). If you take out the ECU-side connector (that's what they should do to check wiring defects) they should read resistance with a multimeter. There is no voltage that comes from the Acc pedal sensor - the ECU reads it by injecting voltage. One can understand lack of knowledge, but one cannot reconcile to lack of sense to access help from elsewhere.
And still they didn't wonder what the error codes were? Time to escalate to TASS! Seems he did the multimeter check, I was told there is variation in voltage. After erasing the error codes, the the throttle works normal, drive for a few mins and the light comes back. This car has gotten me into more of such situations in 2 years than all other cars in 20 years combined, so much for Punto love.
How did they 'drive for a while' if throttle has no response? It is easy to check with a multimeter at the ECU connector end to find out if there is a problem with the accelerator wiring. Even I think ECU is fine, thinking of taking a day off and go sit on the dealer's before he mess up something else. They don't seem to be analyzing them, and the replies given to me vary from day to day almost all of the them circling around accelerator wiring. If the ECU has a serious problem, it wouldn't have started. Neither the accelerator wiring nor the ECU would be a problem. Didn't they tell you what the error codes were before erasing them? Analysing the error codes will help in zeroing in on the problem. the warning light comes on in constant mode to indicate the presence of engine management or EOBD diagnostic errors. Fault indication during operation: - the warning light comes on in flashing mode to indicate possible catalytic converter damage due to misfiring. This is the way the EOBD of most modern cars are programmed to do.įault indication during start up: the failure of the warning light to go out when the engine has been started indicates that there is an error memorized in the control unit. Program Laporan Keuangan Sederhana Restoran. Any idea what could be the possible issue here?Īpparently, your car's EOBD has detected some error and it promptly put the engine into 'limp mode' in which you can limp back home. What they assume now it's an accelerator wiring or ECM issue and checking by replacing them with parts from another car. The car is at the dealer for 3 days, all they did so far as diagnostics is erase the error codes and drive for a while pretty obvious they are clueless. The car does start and stay in idle, throttle has no response at all. Few days earlier the the OBD indicator light (image below) came up in yellow. I have a Sept '09 Punto 1.2 with 30K+ on the ODO. Very common fault for the Grande Punto built from 2005. This Power steering column is a very common problem for the Fiat Punto 1.2.
