Engine code po29


DTC P029 isn't a right code; please send us details about year, model and engine sizes. Also could try turn On/Off the key three times and stay in ON position (dont start engine)... rad the odometer, this showed Pxxxx codes, note and send us again.

Keep in touch.

I have three codes on my car P0128, P0441 and P0138 are these expensive to fix?


Having 3 codes,does not mean you have 3 problems

Only the repair shop you choose, can quote a price

There is no price until you find the issues

No fire to one of the coils which supplies 2 plugs engine light on and running on 4 of 6 cly.


Several possibilities. Internal coil failure, wiring or connection problem, computer is not functioning properly to energize the coil pack. Which two cylinders? I gather the Check Engine light scan reveals misfire codes (DTC) P030? and P030?
Check out the wiring diagram:

Battery No Charge and Error codes


These are for 4.9L


P016-generator voltage out of range--Voltage is below 10 volts or above 16 volts with engine at 500rpm.

P030-Idle speed control (ISC) out of range--Check ISC for operation

A047-very low A/C refrigerant condition warning--check refrigerant level

I039-speed sensing suspension (SSS) fault--this one requires a lot of testing. Could be anything from bad connection at a strut, to bad ground, to bad strut.

I041-battery voltage too low--at 800 rpm, voltage is less than 10.6 volts

I052-keep alive memory error--means IPC lost voltage, and reset. Normal if battery was disconnected, or lost voltage.


These codes are for 4.6L


I039-loss of road sensing suspension (RSS) data--might need to replace rss module

P016-generator voltage out of range--same as above.


If you need anything else, let me know.
